Pond side caved in

How to fix my pond side as it has caved in?

on one side the soil has come down and pushed pond liner so now got a massive bulge on one side

• Here's what I do.
• Buy 26 gauge roofing flashing, 15 pound roofing felt and some 1/2" PVC pipe. 
• Pump out the pond,remove the liner, then make the sides of the pond straight up and down. Run the flashing all the way around, stake it with the pipe, cut to 2' or whatever you need. Bend the top edge of the flashing over toward the outside so it does not penetrate the liner. Cover the entire inside of the pond with 15 pound roofing felt. Now back fill where there is space behind the flashing. Do this carefully so you do not force the flashing to bend in toward the pond. Put the liner back, refill the pond and put the plants and fish back in.

• Good luck.

Drainage and ponds

Question:
If I dig a pond in my side yard will it help my drainage issues?
In my side yard the lawn doesn't drain very well. If I dig a pond in this area would all the standing water run into it since the pond would be the lowest lying area in that the lawn? IF I did dig a pond in this area would there be any legal concerns since this part of our property does not have a fence around it? Would I have to worry about drowning issues and lawsuits?

Answer:

You would be digging a retention pond, not an ornamental pond. You might need a permit, so check with your local building code enforcement office.
You could dig out an area less than a foot deep and put a bog garden there and need no permits or fences.
You might also think about a french drain to help with drainage problems.

Tiny ponds

Ideas for the base of a small pond?

Hi I am going to make a small nature pond, it can't be too big as I don't have the space or money, really it is for dragon flies, and frogs,toads and newts, not fish. I could get a pond liner but its hard to find one which is small so what other kind of container could I use? I have a rounded plastic tub a little larger than a washing up bowl but it doesn't slope like it should to seem natural. Could I get the smallest pond liner possible and just cut off the excess?

Any other suitable container I could use?

Thanks :)

A horse feeding trough is about $40.00 USD at a feed store. They run about 3' across and 2' deep. 

You can also use your rounded plastic tub and surround it with flat rocks that stick out over the edges a bit to hide them. I have made ponds from casserole dishes and even old aquariums. If it holds water, you can make a pond. Just be sure you put the proper submerged and floating vegetation in it and a mosquito fish. Or use a Mosquito Dunk occasionally to keep mosquitoes away.

Pond liners and tree roots

Question:
Have your pond liners been poked by tree roots?
I've got a EPDM liner, and I'm not going to use underlayment.
There are an avocado tree, an apple tree, an orange and a willow. They are about 4 feet away from the border of my pond. The pond is just 15 in below the ground.
I wonder if the tree roots can poke the liner? or it will just run around the liner?

Answer:
Your liner will be fine with those trees. Bamboo and banana trees poke through liners, no others. But it is safer to use an underlayment. Use 15# roofing felt. It's cheap and easy.

Putting stones on the pond bottom

Question:

What stones can I put in the bottom of my new pond?
Can I put pea shingle or similar, I have a mixture of shingle and slightly larger stones in my garden already that I no longer require, so thought I could put them at the bottom of my new pond? I will be getting goldfish for it.
Thanks.

Answer:
Please, no stones in the pond. You will go crazy trying to get them out when it comes time to clean the pond. They serve no purpose at all except to muddy the water. Put submerged and floating vegetation in the pond, then put goldfish in. Don't forget the dechlor.

Hoglice?

Question:

Pond full of Water 'Hoglice'?

Hiya, I have been moved into my parents' house which came complete with garden pond which i know little about. Today i started pulling out some of the pond weed as there is quite a lot,and it is infested with what i believe to be hoglice, the weed is literally running alive with it, it's not something I have ever heard of or come across before, the pond otherwise seems okay, full of tadpoles at the moment and only a couple of fish and some babies which were born in the pond last year. should I just leave these lice? Is there anything I can do to get rid? are they causing harm? 

Hoping someone with pond knowledge will be able to assist on this one as I don't want to completely mess up the ecology of the pond.

Answer:

I would leave them alone. They have a predator:

http://www.unisci.com/stories/20011/0108…

but that predator is invasive and destroying water life all over the UK. I think the ecology of the pond will be fine.

I have a philosophy of benevolent neglect when it comes to ponds and it has served me well for over 20 years.

Natural Bottom Pond

Question:
How do I get rid of the grass in my pond?
I have a medium sized pond that has a lot of fish in it and a lot of grass too. I want to get rid of the grass so I can cast my reel and catch something other then grass and lily pads. What can I use to do this?

Answer:
You will have to rake the grass out. If you want to have a fishing pond, the rules are different than if you want an ornamental one.
Get a small flat bottomed boat and a rake. Rake the grass into the boat and deposit it into your compost heap when you are done. Be prepared for a dirty, nasty job.
BTW, any chemicals that kill the grass will also kill the fish.

Pond Pump Blocked

Question:
How do I keep my 90 gallon pond pump from getting blocked up so often?
I see ponds with waterfalls in parks that seem to run fine all the time. I need to pull mine up and clean all the leaves and other debris that find their way in about once every 3-5 days or it slows down to a trickle. There must be a trick I don't know about since I know not everyone is pulling up their pond pumps to clean them out like this.




Answer:
Small pumps like that are almost impossible to keep clean. They are made for indoor fountains, not outdoor ponds. I would probably try to make a 'sock' for it out of a fine mesh. Be sure the sock material is kept away from the impeller because it will suck the sock right on it. You can make a box out of hardware cloth, cover the box with old panty hose or coarse foam and that will work better than what you have now, but in the long run, you will be better off with a larger pump made for outdoor use. It will probably come with it's own filter.
Another thing to try is to fill up a black plastic grow pot with lava rock and put your pump in the middle of it. That way the lava rock will act as a filter and you will get a longer time between cleanings.
Oh, and elevate the pump so it is not on the bottom of the pond. That will buy you some more time between cleanings.

Pump flow control

Question:
How might you control the pump speed of a fountain in a pond, so that the water doesn't spray too high or how?

Your Answer:
A small pump will have a circular dial to regulate the flow. The larger pumps, meant for outside, have no regulator on them. You can use a clamp which doesn't work very well or you can T off the hose and make two or more outlets to regulate the flow. Just let one hose stay in the pond and hook the other to the statue.

Controlling pond algae

Question:

Has anyone used the Water Wych in their ponds to control algae?

They sell these things at pond supply stores and it shows that you just put it in your pond to help eliminate algae and is safe for plants and fish.

• 
  Answer:
• 
  
• Algae control can be done much cheaper and easier. This is just a box that holds barley and carbon. It will work, but so will barley bales and activated carbon from the fish store. It does not help with blanketweed or string algae. The only thing I have found that works with string algae is Microbe-LIft PL. 

• I wouldn't spend the money on a plastic box when I could put activated carbon in a torn panty hose leg and throw it in the water. Barley comes in its own bag. 
• To learn more about controlling algae, this is an article I wrote: http://www.pondlady.com/Articles/pondalg…

Filter media

Question:
What's the best filter media for my fish pond and waterfall?
I've used Spring Flo Bio Ribbon but am thinking about Bio balls. Do they go in the tank with my pump?

Answer:
I would use lava rock in a bag. It's cheap and works great. I put them in an old panty hose leg and tie it closed. Make it so the pump draws water through it or water is pumped through it and then over the waterfall.

Balancing your pond

Question:

Can I put goldfish in the small ponds in my yard?
I have three or four small ponds that measure anywhere from to four feet across and a foot, foot and a half deep. I want to clean them up this summer and make them look nice and I thought some fish would be a nice addition.

Answer:

These are a few pond rules to know. Makes pondkeeping easy.

Balance your pond ecologically. Use bog plants like irises or umbrella plants. You must have oxygenators or submerged plants. The best is anacharis, followed by cabomba and hornwort. You must have one bunch of these submerged plants per square foot of pond surface. These plants arrive with a rubber band holding them together. Remove the rubber band before you put the plants in your pond. If you don’t want them floating freely, you may pot them up in several pots that sit on the bottom of your pond. The submerged plants are fertilized by fish waste and CO2, a fish byproduct. The fish eat the submerged plants, but they grow faster they the fish can eat them. Nice cycle, huh? Nature takes care of itself if we can j ust leave her alone. If you have too many fish, they will eat all your submerged plants and you have to start over again. A good rule for fish load is 1 linear foot of fish per 25 square feet of pond surface area; tails don’t count. If your pond gets green, have patience. It will fix itself


When pH gets on the basic side algae flourishes. Vinegar is weak and it takes forever (days) to neutralize. But it takes an expert to use muriatic acid properly, so do not put concentrated muriatic acid in your pond to balance pH unless you know what you are doing. You can buy commercial products, usually called pH down or some such. They are expensive, but work well.


It is good to have algae slime on the sides of your pond... this is a sign of a healthy pond and can generate up to 70% of the oxygen needed for your pond.


If you feed your fish, these simple ways of keeping your pond clear will not work. You will need a filter, preferably a biofilter.


You must cover at least one half the top of the pond with floating plants. Parrots’ feather is great, as are water hyacinths, water lettuce and water lilies. If you live in the tropics, you can have beautiful tropical water lilies. You must be willing to either sacrifice them in the winter or store them away until warmer weather arrives again in the spring.

Fish feeding, balanced pond

Question:

You talk about Water lilies on your web site are these your favorites or are these the flowers that generate the most questions?

Answer:

Water lilies? Yes, they do generate questions. But more questions are asked about murky, green ponds which leads to talking about submerged vegetation, the most important plant in the pond.  The water lilies are what sells the pond and are great for providing shade, keeping the pond clear and protecting the fish from predators by giving them a place to hide.

Question:

  I know you feel strongly about not feeding the fish in your pond, can you tell me why this is?

Answer:

If you feed the fish, you introduce a foreign substance. A balanced pond has 1 bunch of submerged vegetation per square foot of pond surface. The fish eat the plants, provide fertilizer for them. And the plants provide 02 for the fish and grow faster than the fish can eat it.  If the fish get fed, they grow too big, the bioload gets too much for the size of the pond. Soon you have huge fish, too much fish poop, not enough 02. The huge fish begin to die and all the fish poop pollutes the water. The pond becomes a great example of how we are polluting our planet.

Question:

 How do you go about achieving a correctly balanced water garden?

Answer:

See the last answer: One bunch of submerged vegetation per sf of pond surface area, at least 1/2 of the pond shaded with floating plants, no fish feeding, no run off getting into the pond, no more than 1 linear foot of fish per 25 square feet of pond surface.

BTW, All the previous information is for goldfish ponds only. A koi pond is an outdoor aquarium and must be treated as such with filtration and food.  If you have a koi pond, you cannot have water lilies nor do you ever need submerged vegetation because those little devils eat it like Hershey bars. Even building a koi pond is different from building a goldfish pond.

Solar pumps

Question:
How to pump water from a stream?
I'm looking for a small pump that can run on solar power and pump water from a tiny stream behind my house straight up about 10' to a barrel that I'll use to water my garden. The trick is it has to be low gallons per minute but also be able to pump high enough and run on solar power.




Answer:
Solar powered pumps are not capable of that. Solar power has a long way to go before being powerful enough to pump a 10' height. You could set up a sump pump in the stream that worked on a timer and pumped water when you needed/wanted it. It would have to be a relatively large pump to have a 10' head, perhaps as much as 2500 gph.

Water plants and soil?

Question:
Do Water Plants work without soil?
I have a small pond with no soil, only pond pebbles. Water is about a foot deep. Will water plants such as lilies grow without the soil? Or do I have to have soil?




Answer:
Pot up your pond plants. They don't need to be in soil, but they do need to be in a pot. Use pebbles if you wish or any old soil you have lying around your yard and put pebbles on top.
DO NOT plant directly in the rocks in the bottom of the pond. The plants will grow everywhere and you will have to get them out of those rocks. If it were me, I would remove the rocks now before you have to deal with cleaning them. But whatever you do, don't plant anything directly in them.

Pond pumps and underlayment

Question:
Pond Pumps: GPH and Water Circulation?
Why does a pump have to circulate 1/2 to the entire volume of water in one hour?
What pond liner, underlayment, and pump would be suitable for a pond 20 X 20 feet that is 3 feet deep?


 Answer:
Use 40 mil butyl rubber for a liner. You can use commercial underlayment or roofing felt. Old carpet can rot and start to stink as time passes.
To find liner size, measure the bottom, both sides and add 6'. I would get a 3500 gph pump so water will properly circulate. Circulating water adds O2 to the water, so the fish can breathe.

String Algae!

Question:
How to get rid of string algae in our ornamental pond.?
We've tried 4 or 5 different chemicals including clarifier and algaecide. We have a barley pad floating in it, we have a fountain running and a creek running into it, we also have about 30-40 comet goldfish and koi, and about 6 plants growing in it as well (water lily, cattails, irises) although they are not fully grown yet. The algae lines the entire bottom and sides and is about 3 inches thick. Would a pond vaccum help? We don't know what else to do :(



Answer:
I have found that Microbe LIft PL works very well to eliminate this stuff. Get as much as you can out and then put the Microbe LIft in according to directions. It's an enzyme and won't harm your fish or plants.
You don't need a pond vac at all.

My pond is losing water

How to arrange my rocks in my pond so they do not splash out and lose water?

The water looks like they are causing me to lose water off the rocks.  How can arrange them so it does not happen?

• 
  The water area needs to be twice as wide as the height of the waterfall. If it is not, the water will splash out. That's one of those laws of physics that none of us can break. Even if the water flow is in little drops, it will still splash out. So lower your water height or make the pond bigger.

Solar Powered Fountains

Question:
How can a pond fountain work with a solar panel?
I try to put a fountain in my garden pond I would like to make it solar powered and don't know how. I’ve see it in garden magazines and I would like to do that in my yard.




Answer:
You can buy them. Oase makes the best one I know. That said, the technology for solar powered pumps is not as good as it could be and the failure rate is high. I wish they were higher on the list of important things to do.

What pump should I buy?

Question:
Hi. I am wanting to find out what pump I need.
I am putting in a garden pond with a waterfall that will come down a 3 ft gradual slope. How do I know why gph pump I need to carry the water back up? Do you recommend filter boxes to protect the pump?

 


Answer:
I would buy at at least a 2500 gph pump. I always suggest that folks buy a bigger pump than they think they need.
Yes, I advise a pre-filter. I like a box because the larger area does not gum up the impeller as fast.

Patching a pond liner

Question:

Is there a paste of some kind that will repair tiny holes in a rubber liner for a pond?

Answer:
There is no paste, but there are patches that you can just attach. The patches are sticky on one side, so get the liner dry and put the patch on. I often help it seal to the liner by blowing it with a hair dryer.

Water Lilies

Question:
How do water lilies grow?

Answer:
They grow just like any other plant, but they grow in water. They grow from rhizomes planted in most any media, need feeding with aquatic fertilizer twice a month during their growing season. That season starts in the spring when the first pads reach the top of the water. They need at least 5 hours of sun daily in order to flower, come in hardy and tropical, night and day blooming varieties. And are beautiful.

koi skimmer, filter, pump

I have read a lot about building a koi pond but i am unsure of where to put the skimmer, filter and pump?

Does anyone have a diagram of where to put all the stuff, preferrably the pond would be L shaped. or can you tell me please because videos on youtube etc... dont really say where the filter goes.

You don't need a skimmer at all. You do need a filter tho, bugt it doesn't matter where you put it. Put it where it is easiest to hide and to clean.

Here's an article that I wrote about how to build a koi pond.

http://www.pondlady.com/Articles/koipond…

Oh and thoughts about skimmers:

DIY underwater lights

Question:
Have you ever made underwater fish pond lights yourself, HOW ?
I refuse to spend 80 dollars or more on little 12 volt LED lamps or other types. What about LED lamps in water-tight containers, SELF made? Has anyone here done it, and what problems did you encounter? The solutions?
Thanks. My goldfish pond is 3 feet deep in the middle, and maybe 6' x 8' rectangle. 33 fish. Some babies every spring.


Answer:
I would not try to make underwater lights myself. Electricity and water together can be deadly. Sealing the lights safely will be impossible. Don't try it.

Water hyacinths

Question:
I live in zone Georgia, zone 8a.
Water hyacinths grow well in my area...just not my pond?

My pond has koi.
My water hyacinths were in floating nets.

They all died in the winter.

Someone said seeds can live under the old hyacinths until spring and then grow.

Haven't seen any action yet.

Normal? Do I need to wait longer? Are they all just dead?



Answer:

Your koi are eating the roots of your hyacinths. No matter what plants you have in with your koi, they will eat and love them.  The floating nets that supposedly keep the plants safe usually don't work very well and koi are pretty smart fish.

Frogs and Toads

Question:

I have a smallish pond (about 330 gallons) and each year we get many frogs and toads. Last year we had huge amounts of spawn, both frog and toad. The pond ended up teaming with tadpoles to the point where I was concerned for the health of my fish (lack of oxygen). The froglets then spread through my lawn making it unusable.
This year we already have even more than last year, and the 50+ frogs and toads continue to mate. Are there any organisations that would re-home the frogs/toads/spawn?

It seems my fish are too small to eat the spawn, causing an imbalance.



Answer:
Toads and frogs are so very valuable. Not very many survive, so please allow them to stay in the resort you have built for them. Tadpoles will not hurt your fish and the fish will not eat the tadpoles either. Nor will fish eat the eggs. It's only for a few days a year and then the mosquito eating critters are off doing their jobs until they return to your house again next spring.

DIY Pond Filter

From Craig Hahn, veteran pond keeper and all around handy guy:

Just thought I might mention a solution that I have come up with - once the ice is off the pond here. (More snow here yesterday. yuk!)

I have a half wine barrel (~20gallons) that I fill with 3" lava rock (to handle the inflow) then use that fiber material that they sell for pillows - still can see the look of the sales lady when I told her I was using this for a bacteria medium). I tip the barrel so the water spills over into the pond and cover the top of that fill material with a layer of foam thick enough to lay flat. I cover this with small - medium rocks to make it look nicer. Then the pond water is forced into the bottom (lava rocks) and is filtered and nutrients consumed when it warms up a bit by the bacteria (I don't add any product - just use nature). You could clean the filter material if you like after the water is cleared but I don't - I love the natural way of things.

GFI reset

Question:
Why doesnt my pond pump work anymore?
I cut my hedge and severed the electric cable causing a fuse to blow, after resetting the trip, everything worked except the pump, even though the socket it was connected to was live, I had not cleaned the pump filter for many months, but I cleaned it all up, I found the impellor will now move, but when I switch on there is no sound or movement at all from the pump, all fuses are ok, the make is Oase filtral 5000 D I need a new pump?

Answer:
Try this: Plug the pump into something else. Put it into a bucket of water or somesuch. If it works, then the problem is in your electrical socket. Also check the outlet for a GFI. It should have one. It will be a red or black button that turns off the pump in case water gets to the outlet. Push it to reset.
If your pump still does not work, you will need a new one. It may be under warranty. Oase has great warranties. Check and see.

Rock fountain question

Question:
Stone rock fountain question?
at a rock store I saw a fountain that was really cool but I can't figure out what it is called. It was just a elongated rock with a hole drilled through it standing up so that it was tall, hooked up to a pump. I just want to know what you would call it and also if you know of any good priced and reliable sites or places to buy them.

Answer:
Most stone yards will drill a hole in any rock you find there. It will cost you a few bucks, but not much. If they specialize in pond rocks, they may have some with the hole already drilled. Just attach a hose to a pump, put the rock in the pond with the pump in the water and plug in the pump. You now have a great fountain.

Algae Control

Question:
Help with pond and summer algae?
I have a 2 acre pond surrounded by mostly trees red (swamp maples) and the pond is mostly fed by runoff at the bottom of a hill, the pond was built in a swampy area (there are a number of seeps in the area, so it is fed by seasonal seeps/springs also) I usually have overflow for 4 to 5 months of the year of at least 10 gpm (more when it rains)...

The trouble I have is in July/August when there is no overflow and I lose from evaporation 3 to 4 feet of water level and the pond develops green algae, I am aware of using barley straw to control the algae, Is there any other methods to help?


Answer:
There are several products made by Microbe-lift that will keep your water clear. I have used many of them and they all work well.  I would start with Microbe-Lift Sludge and then use Microbe lift PL after that.

Keeping mosquitoes away

Question:
Hi. I have a small outdoor fountain. I'm not home a lot of the time, so I don't want it to run continuously. Where I live, Louisiana, we have a lot of mosquitoes, and I'm afraid the standing water will attract them. Does anyone know how I can keep the mosquitoes away without harming birds? Someone told me to use a small amount of bleach, but I'm worried about the birds. Thanks for any help!!

Answer:
There's a product called Mosquito Dunks. Safe for everything and gets rid of all mosquitoes. You can get it at your nursery or maybe even a big box store.

Pond installation cost

Question:
What does a 25 by 25 pond cost if put in by a professional?


Answer:
Somewhere between $20,000 and $25.000, depending on where you live and what jobsite problems might be encountered.

Pond Chemicals

Question:
I use Interpet also know as Blagden chemicals in my pond. I just wanted to know whether I can use several of them at a time, like can I use chlorinate when I refill my pond then also add some plant fertilizer (flora boast)?

Answer:
You need no chemicals in your pond except dechlor to remove the chlorine. Never ever put chlorine in it. It will kill the plants and fish. If you have an algae bloom, you can use an enzyme - Microbe Lift PL if need be. If you fertilize too much at once, your pond will turn green.


Growing Lotus

Question:

I have a water lotus that is rooted and growing in still water but I am wanting to add running water that will agitate the water around my lotus plant. Will this water movement disturb the plants growth? I know plants like the water lily do not do good with water movement.

Thanks

Answer:

Neither lotus nor water lilies like moving water. If you can put the lotus far away from the moving water, you will be OK.

Floating plants

Question:
Are there any plants that float entirely on the water,with roots hanging down?(except duckweed & water sprite)?

Answer:
Mosaic is one. Parrots feather can float without soil as well. Certainly water lilies and lotus need to be in pots or in soil.

How to get a pond clear fast!

Question:
My pond has been murky for about a month now. We put algae killer in but it is still the same. we have fish and frogs in there. what can we do to make it really clear and FAST ?

Answer:
To get your pond clear FAST, you can rig up a quick filter. Put a large plastic pot on top of something in your pond. Be sure it is out of the water. I have used a lawn chair. Put 4" of foam rubber in the bottom of the pot. Run the hose from the pump into the pot. Hold it down with a brick. Be ready to clean the foam rubber every couple of hours or when the water spills over the top of the pot. Your water will be clear in about 48 hours.

Swimming Pool Liner

Question:
Can i make a pond with pool liner?
I bought a 12'x12' pool last year and now it's in the basement put away -
those inflatable pools
Can I reuse it to build a 8'x4' pond with this same liner?
I'll put those rolls you have to put before the liner also.
So do you think it will work? Like I wouldn't see why not and how long would it last? How long would a normal pond liner last?

Answer:
They get brittle when exposed to the sun usually within 2 years. Use a butyl rubber liner - they come with at least a 20 year guarantee. You could use your pool liner for your underlayment.

Concrete pond problems

Question:
How do I keep pond water from going away?
I cement the pond with 3 layers and Im not going to do another one. I have 2 roots in there that I cemented, but Im not sure if there taking in water still. I have 2 layers of brown paint in there and still, the water keeps going away. Help please.


Answer:
Concrete is awful material to use for a pond. It is just too brittle. You need butyl rubber and not bought from a big box store. Google pond liners and have it shipped to you. It will be less than the retail stores sell it for. I would break out your concrete first tho so water does not get trapped between the new liner and the old concrete. And use an underlayment to protect your liner. Roofing felt works very well.

Taro

Question:
I think these plants are like little elephant ears. I need help?
I dont know what they are called but they are little bulbs they looked like little elephant ears but they are red and maybe black? Dark purple, something like that. I would like to know what they are called and also when I should plant them... any help would be awesome, I'm only 21 and im not the best at gardening yet. Thanks


Answer:
It's taro. You can get it in dark dark almost black, striped, or solid green. I have them in the pond. They do have a tendency to jump out of the pond and travel far, so watch out.
The bulbs can be fermented and eaten as poi. Not by me, understand, but by many.
Plant them now if it's spring where you are, but they do come back after a winter....and back and back and back....

How to bid landscaping

Question:

How do I bid some landscaping?
I have some work that a friend wants me to do. He needs a couple flower beds put in with some brickpavers, top soil, and mulch. Should I bid by the square foot or figure out the cost of materials and then estimate the amount of hours it will take?

Answer:
Cost of materials +10%
Labor + costs of insurance and other benefits. Usually 35% of labor costs will cover that.
Other overhead: Cost of gasoline, truck insurance, office costs, paper, pens, computer, etc.
Any other costs included in the job.
Add it up and add at least 15% profit.
That should do it for you.

Natural Pond

Question:
How to revive my natural pond?
We purchased a house about 2 years ago. The people who lived here before us did not take care of the property and left the place in pretty bad shape. There is a natural pond in the back that is scummy, full of all kinds of plant life, and during the summer can be pretty stagnant. It is a large pond about 5500 sq ft. There are lots of frogs and turtles and toads in it but really no fish. It is natural so there is no liner concrete, rubber nothing, just a dirt bottom. The tributeries leading away from the pond dry up and are just a hunk of scum during late summer. We were told that the people before us rerouted waterways dealing with this pond, but we do not know for sure. We really have a lovely piece of property and would like our pond to be clean and pretty. What can I do to fix this problem? I have searched on the web and only found things dealing with man made rubber bottom or concrete ponds.

Answer:
Start by raking out all the old plant material. Wash it off and put back about half of it. After that, put in a floating pump to circulate the water. Plant around the edges with natural bog plants. If you put fish in, use goldfish only and do not feed them.

Growing calla lilies

Question:
How to grow calla lilies?
I'm going to try to grow some calla lilies this year...I already have the bulbs...and I was just wondering if you can give me some tips...

Answer:
Put them in the ground as soon as you can work it. They love filtered shade and even more love to have their feet wet. I use them in shade ponds when possible. The flowers are incredibly gorgeous. Good luck.

Pond pumps

Question:
Do I need a pump for a pond?
I am using it to grow lotuses, but I also want to add a few goldfish to it to make it more interesting. Would I need to buy a pump for the fish, or would the plants provide the oxygen needed?


Answer:
You don't need a pump for your pond. If you add goldfish, you must add submerged vegetation for them to eat, but never feed them anything else or the water will get foul. The submerged vegetation (anacharis, hornwort, cabomba) will add enough O2 for the fish.
Add a few mosquito fish to keep mosquitoes away.

Cal Pumps

Question:
Does a cal pond pump make noise when on?
We have a pond and bought a cal pump for the filtration of the pond and was wondering if we'd know that it was on. Does a cal brand pond pump make any noises, such as a running noise? Also, how do I work it? how to turn on, keep on, and how to get it working.

Answer:
Calpump makes one of the finest pond pumps. It makes no noise at all. You can feel it humming if you touch it, but that's it. To work it, drop it in the water, and plug it in. Hook it up to the hose you want it to pump water through before you put it in the water. I would use a prefilter to keep debris out of the impeller.

Koi and filters

Question:
Is it possible to turn a pool filter into a filter for my Koi pond?
I know i can't use the sand in it, I will take that out. What type of media should i use?



Answer:
Yes it's possible, even recommended. If you want to take it out, use lava rock, beads or bioballs instead.

Fishing pond

Question:
Can i put a pond in my backyard? (for fishing)?
hello. i live in ohio and i want to put a pond in my backyard but i want it for fishing. what can i do to have the pond without hitting any lines of pipes?

Answer:
It can be done, but it's not easy. First call your local utility company and have them mark where their wires and pipes are.
After that, find a local aquaculture place and ask for help as far as how deep it has to be, and what you can stock successfully, etc. Usually a local community college can help as well. Another resource is your local extension service.

Wetland Gardens

Question:

How do I create a wetland garden?

We live on a lake in Michigan and I want to start planning a wetland garden. We have an area by the lakeshore that is always mushy, so I'd like to embrace mother nature and plant a wetland garden in this area that will look better than muddy grass. And I would hope this area would improve drainage in my yard. How much maintenance does this type of garden require? What mulch or other bedding material would be best? The area is probably 30 ft long by 5-8 feet.

Answer:

Here's an article I wrote about building a bog garden.

http://www.pondlady.com/Articles/bog_garden.html

In Michigan, my home state, I would use cattails and hardy rushes. Drainage would indeed be improved and the area would look nice. Maintenance would be very little. I mulch mine a couple times a year.

Ponds and pumps

Question:
Is it possible to have 2 ponds running off 1 filter & 1 pump?
i want to add a second pond ,but i would like to know if it is possible to use just 1 filter & 1 pump ? if so how do i do it or do i need to use 2 pumps & 2 filters i should also say that i want to run a waterfall flowing down into the bottom pond from the top 1 any info would be much appreciated many thanks

Answer:
I suppose it is possible. You would have to use an inline (out of the water) pump and somewhere in the hose put a Y so each pond could have water moving. To get two waterfalls, you would need a HUGE inline pump, but they are made, I know. You could use one bead filter that was also out of the water. You are looking at lots of dollars. It would be cheaper to use two pumps, I think.
That idea of having one pond flow into another one is very very difficult to do. I built ponds for 20 years and when doing that sort of thing, I made each pond a separate entity, each with its own pump/waterfall.

Oxygenating grasses

Question:
Can you plant just regular grass seed in a fish pond? Will it grow? Will it take oxygen from the fish?
I own some land in which I have started building a fish pond. If the grass doesn't grow, is there a special type of underwater grass to use?


Answer:
Regular grass will not grow in water. Use anacharis, hornwort or cabomba and your fish will love you. All three give O2 to the fish and they, in turn, fertilize them.

Terra Cotta Fountain

Question:
What type of pump do you suggest for a terra cotta pot fountain?
It is going to be made of three pots staked on top of each other with a saucer on top.

Answer:
You can buy a tiny one at some place like Hobby Lobby that costs less than $20.00. You will have to replace it often because those little ones don't have a long life. But anything bigger will send the water into your neighbor's yard. Have fun with your garden art.

Koi pond filter

Question:
I have read a lot about building a koi pond but i am unsure of where to put the skimmer, filter and pump?
Does anyone have a diagram of where to put all the stuff, preferrably the pond would be L shaped. or can you tell me please because videos on youtube dont really say where the filter, etc. goes.




Answer:


You don't need a skimmer at all. You do need a filter tho, but it doesn't matter where you put it. Put it where it is easiest to hide and to clean.

How to build/buy a small raised pond?

Hi I bought my partner two goldfish and a fishtank for Christmas last year, one is your average goldfish (Betty) and the other a Sarsha comet (Bob) They have been living in a 10 gallon tank this whole time and as a random surprise I want to build a raised bond in our back garden. It has to be raised as we have nephews who visit and we own a lot of rabbits.

The garden has mostly been taken over by the bunnies but was planning on putting it near the patio part. Is there any like metal tub/plastic tub ponds that I can put there? And what sort of size should I be looking for and what sort of filter?

Thank you


You can build or buy most any size pond for the back yard. Here's one made of cinder blocks and fieldstone. Or you can use a circular horse trough, bury 24" of it and camouflage the rest.
Here's an article with photos for the cinder block pond.

Koi question

I live in miami fl. im building a 175 gal waterfall pond but can go only 20 inches deep. I have morning shade?
Question: I am concerned about the temp for goldfish or koi in summer. I have a concrete pond I bought as a foundation. It's only 45 inches round and 8 in deep, so I plan on dropping it under ground 1 foot and adding 1 foot around the circumference. This should take its original size of 65 gallons and add about 100 gallons more making it about 165 total make any sense got any ideas?





Answer: Your fish will be fine at 20". I would stick to goldfish rather than koi, tho, because koi need at least 3' of water depth. Cover 60% of the top of the pond with floating vegetation and put in one bunch of submerged vegetation per square foot.

Koi and pumps question

Can I turn off my pump in my koi pond in the winter?

I have a leak in my pond liner. I think it is at the bottom because a windstorm moved a large plant and my water level started to drop after that. The temperature where I live is from high 30's at night to 60's during day. Can I turn off my pump and let my water level drop without depriving koi of needed oxygen? Also, when I remove koi to completely drain pond, how long can they survive in small holding tank w/o pump

If your temps stay under 55F, you might be safe turning off the pump, but I would probably throw an airstone in the water. Frankly, I suspect you will not find a leak at all. First turn off your pump and watch the pond overnight. I'll bet the water level will not drop and you will find that same wind moved hoses around and the water is dripping off the back or side of a waterfall.
With an airstone, the koi will survive in a kiddy pond for as long as you need, especially in cool weather.

See my article on leaking ponds: http://www.pondlady.com/Articles/pondlea…

Make your own pond vacuum cleaner

One of our readers made his own pond vacuum cleaner. He reports it works great and was cheap to make. He graciously shared how to make it with the readers of pondlady.com. I though it would be nice to post it here as well for readers who do not get to pondlady.com regularly.

Thanks for sharing, Darrel. We all appreciate it.

From Darrel:

Here's a list of the parts I used:
(1) Utilitech 0024840 Lawn Pump or Flint & Walling/Star Water
#HSPJ100(any 1hp utility pump with 1" intake/outlet)
(1) Culligan HD-950 Whole House Water Filter
(2) Union 1" slip X slip
(4) 1" male adapter, 1" slip socket by 1" NPT
(1) 1" 90º elbow slip
(1) 8 ft. of 1" spa flex hose
(1) 10 ft. of 1" PVC pipe
(1) 1" coupling
(1) Circular brush attachment from a vacuum cleaner to fit the PVC pipe.

Procedure:

The filter is attached to the inlet side of the pump.
(1) Screw a male adapter into the pump inlet.
(2) Cut about a 2-1/4" piece of PVC pipe.
(3) Glue this into the male adapter.
(4) Glue one side of one union to the pipe.
(5) Screw a male adapter into the filter outlet.
(6) Cut another 2-1/4" piece of PVC pipe.
(7) Glue the pipe into the adapter.
(8) Glue the other side of the union to the pipe.
(9) Screw another adapter into the filter inlet.
(10) Cut another 2-1/4" piece of PVC pipe.
(11) Glue the pipe into the adapter.
(12) Glue one side of the other union to the pipe.
(13) Glue the other side of the union to the spa flex hose.
(14) Glue the coupling to the hose.
(15) Cut a 6' length of PVC pipe.
(16) Glue the pipe into the other side of the coupling.
(17) Screw an adapter into the pump outlet.
(18) Cut a 2-1/4" piece of PVC pipe.
(19) Glue the pipe into the adapter.
(20) Glue the 90º elbow onto the other end of the pipe.
(21) Glue the remaining PVC pipe (approx. 2') to the elbow.

You want the filter on the intake side of the pump so you're not sending crud through the pump. There's also the possibility that if you suck up something living, you may be able to rescue it from the filter housing.

The pipe for the wand should not be more than about 6' or it bends too much and is difficult to control.

Lawn pumps need to be primed. They have a port for priming. You can also fill the pump/filter/pipe with water from a hose, or by scooping it from the pond. Just know that the pump, to begin with, will not suck the water up by itself.

You may notice that I used two additional male adapters, one on either side of the filter. This was only because the store had only one slip union. I had to buy one 1" slip union and one 1" NPT union. I then mixed the two halves of the unions so that each one became a 1" NPT X 1" slip union. The additional adapter then screwed into one side of each union.

When glueing the flex hose to the union hold it for a long time. The glue does not seem to set as fast as on the PVC pipe.

I've included a picture to help.

BIG fountains

I often get questions about huge fountains.  People try to put a fountain in a large pond, usually a natural bottom pond and find that the pump clogs up fast and the fountain stops working.

You will see fountains like the one in the photo at shopping centers and casinos.  This one is near a shopping mall near my house.  If you look closely, you can see that the fountain floats.  At no time can a huge fountain like this one be on the bottom of any pond or it will try to suck up debris and burn out quickly.

If you have a huge pond at home and want to use something like this, watch that the wind does not blow the water out and cause the level to drop to dangerous levels.  Sometimes you have to give in and install a float valve to keep the pond full of water.

Turtles in the pond

We haven't talked about turtles in awhile. Don't get them for your pond. 

Nuf said? No?  OK, turtles eat everything in the pond. They start with your most expensive plants, like tropical water lilies and eat their way through every last plant.  And they do it fast.

You can have turtles in a pond if you have nothing else in the pond. You have to feed the turtles and make a little island and/or ramp so they can get in and out. Turtles do not live underwater.

In the winter, they burrow in the leaf mold and under the rocks and stay there undisturbed until spring when they wake up with a voracious appetite for more water lilies.

Turtle on a turtle?  Yup, it is.

Another kind of pondless waterfall

Most pondless waterfalls are holes in the ground filled with rocks or a box that makes the sound echo.  All nice and all with their own problems.  Yesterday I decided to make my own pondless waterfall in the front yard.

It could be a pond with fish and plants, but it is really small, so I now have my own mini pondless waterfall.

Here's how I did it:  I bought a 3' in diameter x 2' deep Rubbermaid horse watering trough at a feed and seed store.   It cost about 40 bucks.  I had a pump lying around from my active pond building days. It's a 700 gph Little Giant submersible.  I also had rocks in the yard, saved from my pre Katrina pond and moved to this house from the one that we had to bulldoze.

First was a hole in the ground. I did not bury the horse trough all the way, but left about 6" above the ground. It's easier to deal with that way, easier to keep level and doing it like that avoids any run off.  Also with our water table so high, digging a 2' deep hole would find me in the water before I got all the way down.

After you dig the hole, put in the horse trough and fill it with water.  If you don't it will rise like the phoenix while you are leveling it.  Add kiddie play sand around the edges to give a solid surface to hold the trough.  Use water to pack down the sand. As you doing that, get the trough as level as you can.  You will cantilever rocks over the top later, so you don't have to be perfect here.

Start piling up flat rocks to hide the sides of the trough that is above ground. Doing this will make the pond look natural.  Save a spot for the waterfall.

Attach flexible tubing to the pump and then T off with a hard plastic T fitting  like plumbers use.

Put the pump in the water.

Now build your waterfall on one edge of the trough.  Use a large flat rock for the bottom, put a few thicker rocks on top and add another rock on top of those.  That's about as high as you can get because you don't want water splashing out.

Place the two hoses on the top of the waterfall.  Maybe one hose on each level.  Whatever pleases you.  Put rocks the same thickness as the hoses on either side and a rock on top to keep them where you put them.

Now arrange the hoses so no water slides off the back or over the sides and out of the trough.

Hide the hoses in the back of the falls with rocks or plant material.

Use swimming pool chlorine to keep the water clear.

There, you have it and it only took a few hours.  This one took me about 5 hours yesterday.  I am moving a bit slow this morning.

Winter Pond Care - Plants and Fish

Winter Pond Care - Plants and Fish

Reposted for those of you who missed it the first time.

Water Lilies in Winter

Hardy water lilies will survive the worst winter you can imagine.  I have seen hardy water lilies in Rocky Mountain National Park at about 11,000 feet.

 Remember water lilies are only pretty weeds, invasive and obnoxious if left to their own devices.  If you have planted them on the bottom in the bottom of a natural pond, you will regret doing that because they will cover your pond in short order. BUT they will survive. And survive. And survive.
You can tell the difference between hardy water lilies and tropical ones easily. The tropicals have stems that raise the flower far out of the water. The hardy lily flowers sit very close to the water, sometimes even touching it.

All water lily flowers live for about three days and then die. Another opens and so on, so you have flowers throughout the spring and summer.

If you have tropical water lilies, you must protect them in the winter.  If you have a deep pond, you can lower them to the bottom and keep your fingers crossed.  Here in South Louisiana, that's what I do.  Our freezes are relatively short and rare, so our lilies are safe.

If you live where your pond may freeze solid, you can remove your tropical from the pond, remove its leaves, rinse the corms off and pack it in damp sand.  Put it in the garage or somewhere that does freeze. You have about a 50/50 chance of saving your tropical. In the spring, simply pot them up again and place them in the pond.

 Of course, the ideal way is to have a green house and store the lily in it.  You can cobble together an 8' long box made of 1' x 12' lumber, line it with butyl rubber, fill it with dechlorinated water and your lilies will love you for it.  You will have blooms early in the spring.

No matter where you live in the US, your lilies are dormant by now. They react to the length of daylight and dark as well as temperature changes.  Don't worry, you will see them again in the spring.

Ponds, men and women

Have you noticed? I know I have.

When men build ponds they want technical, complicated things like automatic water levelers. Women just use a garden hose to top off the pond every couple or months.

Men will run PVC pipes from the house hose bib and put a faucet near the pond. Women: See above.

Men plumb a waterfall with that same PVC pipe, so if it needs repair, you need a saw, sandpaper, more PVC pipe, fittings and that blue glue. Women use flexible tubing. If it breaks, they get a new piece for a couple of bucks.

Men hard wire a pump into an electrical box, so when the pump burns out, an electrician is needed to install a new one. Oh, and hard wiring the pump voids the warranty. Women just plug in the pump. When it burns out, they just plug in a new one.

Men love concrete. They use it to cement down rocks around the pond and try to glue waterfall rocks together. Women simply balance the rocks properly, so no concrete is necessary. That way, if rocks need to be moved, they can be picked up and  moved.

Anyone else find this strange?  Or is it just me?

Pond Vacuum Cleaners Redux

I get questions about pond vacs all the time. People want to use a pond vac or a wet vac to clean the bottom of the pond and not have to do a total clean out.  And will that work?  In a word, no.

A pond vac sucks up water.  It sucks up the junk at the bottom of the pond, but it sucks more water than junk.

The other big problem with pond vacs is that they do not have enough suction to reach from the top of the pond where they must sit to the bottom of the pond where the junk is.  Wet vacs are better at this, but still not the best.

 If you want to clean the bottom of the pond and not pump all the water out of the pond first, try this: Go to the swimming pool supply store.  Find a gadget that looks like the picture in the link above.  Do not buy the mesh bag that the salesman wants to sell you. It doesn't work because the mesh is not fine enough.  Also, if you don't already have a telescoping pole for your fish net, buy one of those as well.
When you get the saucer/vacuum cleaner home, attach your garden hose to the fitting on the saucer and a leg from an old pair of panty hose over the hole in the middle of the blue saucer.  You now have a water pressure powered pond vac that will (sorta) clean the pond bottom. At least it will do a better job than the ones you pay lots of big green dollars for.

Put the saucer on the bottom of the pond.  Turn on the water.  If you turn the water on first, you will start the job wet.

Using the pole, which also has a handy place to attach, start vacuuming the bottom of the pond.  The panty hose will fill up fast with all that pond scum on the bottom.  You will quickly have a panty hose leg full of decayed plant material, fish waste and other unspeakable stuff that drops to the bottom of the pond.

When the panty hose leg gets heavy, turn off the water and empty the panty hose leg.  Repeat until the bottom of the pond is as clean as you want it.

By the way, I put a water shut off valve at the saucer end of the hose so I can turn off the water without having to walk back to the hose bib every time.

This is a dirty, messy job.  Wear old clothes and be prepared to shower immediately after.

Pond still losing water

You are pulling your hair out trying to figure out why your pond is still losing water.  Do you have a fountain in the pond?  If so, make sure the fountain is not too close to the edge and water is splashing out.  Check your waterfall as well. If water is splashing on the rocks near the edge of the waterfall, it is splashing out.  Falling water must have an area twice as wide as the water is high for the water to stay contained. So if your waterfall or fountain is pumping water 2 feet above the pond, the pond must have 4' of surface for it to fall into.  
One more thing:  If you have a fountain with some sort of nozzle or a spitter that sends water far in the air, the wind can blow the water out of the pond.  Watch your pond water level when the wind is blowing. You might want to turn off your pump if it's windy.


The holes in a nozzle can get clogged up and pretty soon you have one thin stream of water shooting out. It is hard to see because it is so thin.  Check it. You may wish to remove the nozzle completely.   Or clean it lots and lots. With a toothpick. And a brush. In the water. With your boots on.  Frustrating.

Help, My Pond is Still Leaking

You have checked everything. There are no liner holes, the waterfall water is falling in the pond and not sneaking off the back, all hoses and hose connections are tight and secure, but your pond is still losing water.

Do you have a spitter? A spitter is some ornament, often a statue of a frog or bird that has a hole in the bottom and spits water out of its mouth.  I am not a big fan of spitters, but you are and you have one.  First disconnect it. If the pond water level stays put, you know that your spitter is the cause.  Often as pumps get clogged up or hoses get full of algae, the water flow slows down and the spitter drools. When that happens the water sneaks out of the pond, sometimes only a drop or two at a time.  If you don't think that is very much, let water drip slowly out of your inside faucet and see how much your water bill goes up.

To repair a spitter drool, you can move the spitter so it sits totally inside the pond or prop it up next to the pond with a serious tilt into the pond so water can't escape.  Watch out for this method because the thing can fall into your pond and puncture the liner. Then you have bigger problems.  My solution. Disconnect the spitter and let it sit wherever you wish minus the water coming out.

How to Patch a Liner

I always recommend using a 40 mil butyl rubber liner when you build a pond.  Unless you walk on them with golf cleats, they survive most anything.  But occasionally, they get a leak.  If your lab loves to play in your pond, those toenails could cause a leak.  One time I had to deal with a client who put sharp rocks in the pond and put plants on top of them.  If you must put huge, sharp rocks in the pond, put an extra piece of liner underneath and don't move the plants around by just sliding them. Pick up the plants and the rocks if you must move them.
The hardest thing to do if you have a hole in your liner is finding it.  See http://www.pondlady.com/Articles/pondleaking.html for hints on finding the leak.
After you find it, be sure the liner surrounding the hole is clean and dry.  If you are not in blinding hot sun, you may need a hair dryer to get it totally dry.
The 40 mil butyl rubber liner is the same material as an inner tube, for those of us old enough to remember those.  You can use a tire patch found at any automotive store or you can buy patching material from an aquatic nursery or online from any pond supply store. It doesn't' cost much. You simply cover the hole with the patching tape - it's sticky on one side. And you are done.  I have had patches last for over 10 years so far.
So find the hole, slap on the tape, make sure it's dry,  refill the pond with water and  you are good to go!

Catching Goldfish

I have had a few questions about ponds freezing solid.  What to do with the goldfish?

You have to catch them and bring them inside.  I have heard that goldfish can freeze and survive, but have never seen it happen, so bringing them in is best.  But first, how to catch them?

Try this:

1)Fill a container with pond water.

2)Get a bucket of very warm, even hot, water.

3)Pour it slowly into the pond. The fish will come toward the warm water.

4)Use a net, catch the fish and put them in the container full of pond water.  Water is heavy so don't make the fish container too big or you won't be able to carry it.

5)Let the fish warm slowly in that same pond water before you transfer them to their winter home.

By the way, if the pond does ice over, do NOT  hit it with a hammer to open a hole.  The blow could kill the fish. One way to open a hole is to put a pan of hot water on top of the ice and let it melt.

Leaky liners

I know we have talked about liner leaks before, but the question keeps getting asked: How do I fix my leaking pond?

First of all, your pond is probably not leaking. I always tell people that when they call to tell me their pond is leaking.

"Hi Jan, my pond is leaking."

"No, it probably isn't."

"But it is losing water every day and anyway how can you know that if you haven't seen it?"

"I have seen thousands of ponds and am all knowing.  Chances are about 99% your liner has no hole in it. Let's troubleshoot.  If I have to come over there, you will need to get out your checkbook, so if we can do this over the phone, my advice is free.  Which do you prefer?"

"Over the phone."

"OK, turn off your pump, fill up your pond and let it sit over night.  If the water stays put, your water is falling behind the waterfall.  If you have a spitter, the water is drooling down the spitter and out of the pond. Check your waterfall rocks. Chances are one of them has tipped and water is not going back in the pond, but falling off the back.  Look at the water level in the morning and call me back."

I usually get no call back.  The pond owner has learned something.  Liners rarely leak. They rarely get holes in them unless raccoons have been marauding through the water in search of tasty morsels.

The pond owner finds the wayward rock, tips it back into place and all is well.
