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.

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.
