Scum on Koi pond

Question:
Koi pond problem, Help?
My pond has got like a bubbly scum on top of the water. Fish are sitting at the top of water as if looking for air. Pumps and filters running as they should be. This has appeared over the last 2-3 days. I have lost 2 fish and it is not looking very promising. Any help would be grateful. Thanks.


Answer:
If you have lost fish, they may well be sick. Check at koivet.com for help.
It also sounds like your bioload may be too big, ie, you have too many fish or they are too big.
Has hot weather just arrived and the pond is heating up?
Try Microbe-Lift PL to clear the pond and to add some beneficial bacteria. That should help.
You can also swap out 25% of the water. Don't forget to add dechlor.

Ponds and safety

Question:

How can i build a safe small garden pond?

i would like to build a pond in my garden but i am worried about my younger brother falling in. i want to keep guppies, sword-tails and terrapins. something small and easy without too much maintenance would be ideal. also, i cannot buy filters or pumps. oh and it would be cool if frogs lived in the pond =) thanx!

Answer:

You can have a pond in a casserole dish if you want. You do not need a pump. Use submerged and floating vegetation to keep it clear. A mosquito fish or Mosquito Dunks will keep mosquitoes away. Tropical fish will not do well outside. Think a goldfish or two.

Murky Pond Water

Question:
Why is my koi pond water grey?
I checked my pond ph and it was around 8-8.5.
I did a partial water change and now the pond water is a grey/smoky blue color.
2 fish died.
I'm assuming it was a sudden ph crash, but does adding a little tap water change the ph that much?
What do i do?
Are there chemicals i can add to balance the ph?


Answer:
Sounds like you needed to add dechlorinator when you added the tap water. The chlorine in tap water can kill fish as can any rapid change in water temperature.
I doubt it was a pH crash that killed the fish.
You can add vinegar to lower the pH. You can also use muriatic acid, but you really need to be careful with that. pH down is a swimming pool product that will lower pH as well. I use vinegar.
he murkiness is probably because of stirring up of the water. See if it settles down after a few days. But put dechlor in there now or you will lose more fish.

Tadpoles

Question:
Black commas in moving water?
There were these... thing animals that were in the pond where the water comes out from. I thought they were mosquitoes but they were where there was moving water. They are tiny like probably less than one centimeter and they were moving. Any ideas?


Answer:
Tadpoles, either frog or toad. If they are gone in 3 or 4 days, they are toad tadpoles.
If they stick around for a couple years and get bigger and bigger, they are frog tadpoles.

Pond plant growing media

Question:
Are there pond plants that do not require any dirt/growing medium.?
I bought a 'drop in plant"  at Home Depot.  Just drop the plant enclosed in the net and it will grow. They just had one like that. Are there others that I don't have to plant in pond potting soil that I can just drop in the water. I have a 60-gallon whiskey-barrel type pond.

Answer:
No pond plant really needs potting soil. We use it because it's handy and we are used to using soil. You can use any medium to hold the plant in place. It derives its nutrients from the water, not the soil. I have seen rockwool used, kitty litter, sand and rocks. The only general rule is that the top of the pot is about 1" below the water surface.
Your plant was in a growing medium in the net.  You just couldn't see it.

Pelicans and Ponds

Question:
I have a fish pond in my back yard. With four (used to be five) big fish. There is a pelican that lives around my house that has killed one fish that I know of. How with out killing the bird can I protect my fish? I have a net over it but this is not visually pleasing, are there methods or devices made for this problem?


Answer:
There are several ways to keep predator birds away from your fish. One is a motion activated device called a 'scarecrow.' It shoots a stream of water at any intruder...you included if you don't forget to turn it off.

"Gator Guard" is a floating alligator head that works very well.

Some folks cover their ponds with netting, but I think that looks ugly.

Be sure there are plenty of places for your fish to hide. Under flat rocks that are on top of cinder blocks. Put in plenty of submerged vegetation. If you feed your fish, they come to the surface when you walk up. They can't tell the difference between you and an intruder, so they come up when the bird appears. Think about not feeding your fish, unless you have koi.

Pump is not pumping

Question:
My fountain pump is not pumping.
I've filled the fountain with water but pump is not pumping.




Answer:

First of all, plug the pump in somewhere else to make sure the outlet is working. Plug it in while it's in a bucket or pot of water. Does it work in there? If not, check where the intake is. In there is an impeller, like a propeller except it sucks water in instead of pushing it away. Is the impeller turning? If not, unplug it and try to loosen it up with a screwdriver, turning it like you do a garbage disposal when it stops working. Now put it back in the bucket and try again.
If it is working in the bucket, it's not going through the tubing in the fountain. If it's a huge fountain check all the plumbing fittings and hoses. If it's a tiny table top fountain, check the fittings as well. On small fountains there is a place to regulate the flow. Check that - it's usually something circular where you can turn the water higher or lower.
If none of those things work, return the pump. It's faulty.

Lilies in deep water

Question:
How can I grow lilies in a 6 foot pond?
It's 6 ft deep and 5 by 6 I think? My family wants to grow water lilies.  How can you do that in such a deep pond?


Answer:
Lilies like to be at about 3'. I would put some painted cinder blocks or other pedestal in the pond to put the lily pots on. They will be fine. Paint the cinder blocks to keep them from leaching lime. You can use any spray paint and they will not be toxic.

Bog garden spot

I have a spot in my yard that stays wet all the time... what could it be?

Its not the septic tank.  I have no leaks from a water line because my bill is low. There is a spot that just stays wet. What could it be and how could i "dry it up"?

Could it be a natural spring? and if so what should i do? )r could it be something completely different?

• 
  
  It could be that the water table is high in your yard and your yard is a bit low there. I suppose it could be a spring. I would build a bog garden and take advantage of it. Here's how:

Pond plants

Question:

What garden pond plants are best for zone 5?

I have about a 350 gallon pond with a waterfall. The pond is lined. 

What plants can be used with a lined pond given there is no soil at bottom to plant anything in?

Answer:

In a lined pond, put your plants in a pot or leave them in the pot they came in. Make sure the top of the pot is about 1" below the water surface. Tropicals like lotus or tropical water lilies will not do well where you live, but there are many aquatic plants that will. Hardy water lilies will be wonderful and make it through your wicked winter. Here's an article I wrote about more hardy pond plants:

Ponds on Deck

Question:
How do I make a pond on my deck/porch?
My back deck has a gate and lately I've been thinking about putting a pond back there for my turtles.
I have several questions so I'm hoping someone can help me out a little . . .

I've been thinking a lot about the container:
Maybe I'll get an old metal wash tub. Or I could get a barrel, cut it in half and build a wooden frame for it. Or possibly just buy a preformed pond from Home Depot and use it.
The only thing I know for sure is that I want my pond to be unique.

I've also been thinking about shade, would plants in and around it be enough?

And can this only be a summer thing? Or is it possible for the turtles to adapt when it starts to get cold again?

Any info/ideas would help me.
-Thanks so much!!!

Answer:

There are several ways you can have your pond. I would advise against any preformed one from any big box stores. They are flimsy, crack and break in a season.
Rubbermaid makes horse drinking troughs in several sizes. They run maybe $40.00 and hold up forever. You can have a pond in anything that holds water.
You could cut a hole in your deck, put a base underneath the pond and have your pond even with the deck, or maybe 6" above it.
Plants around it would be fine, but I would also add aquatic plants in pots in the water for additional shade.
It would depend on where you live if you have to take it down in the winter. If the pond would freeze solid, yes, the water would have to come out and everything in the pond as well. Heaters work, but not well enough if the pond is above ground and the weather is below freezing for days/weeks on end.

Ponds, pumps and chemicals

Do I need a pump for a backyard pond?
We have a already built three level pond. We didn't built it it was here when we moved in. I was wondering a few things.
1) Can we fill it and keep fish and plants in it without using a pump or filter?
2) How complicated is it to hook up a pump or filter for one?
3) Are there chemicals I could add to keep water looking good without using pumps and still put fish and plants in it??
4) Do you know any good sites that tell u about backyard pond maintenance?

Answer:
1) You do not need a pump/filter if you don't want one, but you must use proper submerged and floating vegetation: One bunch of submerged and at least 60% of the top of the pond covered in floating vegetation.
2) It is not at all complicated. A pump with a hose that runs from the bottom to the top. Check your height and get a pump that has enough head to pump the water high enough.
3) No, if you want fish, you cannot use chemicals.
4) Yes . Mine: http://www.pondlady.com
I look forward to seeing you there.

Toads and the Pond

Question:
How to attract toads to your backyard?
I love toads and I have had many pet ones, but I really want to attract them to my backyard. I have 2 big dogs, a pond with a waterfall with lots of rocks around it but not any plants except for grass and I want to know how to attract toads to my yard.

Answer:
If you have a pond, you will have hundreds of toads. They will begin arriving soon, will sing out mating calls and lay eggs in your pond. Then you will have more toads than you ever dreamed possible, and fewer mosquitoes and flies.

Troubleshooting Small Pumps

Question:
Sarah Peyton Step Garden LED fountain help?
For Mother's Day I bought a little Sarah Peyton Step Garden LED fountain. Well, I decided to give it to her early. It would appear that we need some trouble shooting. After adding the batteries, water and rocks all we get is the light. No trickle trickle of soothing water! Nothing in the instructions explains this or troubleshoots this.


Answer:
Water needs a tube to get from the pump to the top of the fountain. Perhaps it is detached or missing altogether.
First check to see if the pump is working. Touch it. If it hums, at least it is running. Then check the bottom where the water is pulled into the pump. There is an impeller in there - looks like a propeller, but pulls water in rather than pushing it out. You may have to remove the pump and put it in a pan of water to see if the impeller is working.
If you want to try to fix it, remove it from the water, unplug it, and use a screwdriver to free it up so it spins. Then put it back and see if it's working.
If it is pushing water out, then check any tubing that is attached to it to make sure it is attached where it is supposed to be.
If it is not working, rather than try to repair it, I would return the fountain for another one. Those little pumps fail repeatedly, so start with a new one that is working.

Fire Feature in the Pond

Question:
In-pond propane fire feature?
I'm a mechanical engineer and want to add a very unique flare to my back patio. I was trying to decide between a pond and a propane fire feature (in a rock bed) when I was struck by an idea...could I put a propane burner of some sort under the water in a pond and so the gas would surface and produce a flame? I know I've seen it on a large scale (Disneyland), but does anyone know of this being done in residential application? I realize lighting the fire may be a trick. Perhaps an electronic igniter just above the surface? Flow would probably have to be enough to keep a continuous stream of gas through the water or I expect the fire would go out between bubbles. Input or other fun ideas?

Answer:
If it's been done, you can do it. My suspicion is that Disney has a small pipe going from an exterior propane tank through the water and stopping at the surface, perhaps even sticking out a few inches. The public can't see it, but it has to be there.

Turtle pond

Question:
I made a pond for my turtles, what can I put in it so the have a dry floating area to sun?
I bought a pond that is 140 gallons at Home Depot, set it up with the pump, filter, fountain, and put some rocks at the bottom of it. At the moment I have my three turtles in a tank inside of my house, and I want to move them to the pond. Is there a company that offers floating turtle "islands" that I can put in the pond so they can sun? I bought the one from the pet store, and they are so big it sinks when they get on it.

Any suggestions would be great. Such as the company that sells them, etc.

This is the first time I am putting my turtles in a pond/ caring for a pond. Any tips would be great too.

Thanks!!!

Answer:
A rubber pad like you kneel on in the garden (if you are old and have bad knees like one of two of us have) will work well. If you need more than one, just cable tie them together where the handle is.
I would think about just putting a log in there just like turtles have naturally, so they can pull themselves out of the water to sun themselves.

Because you have turtles, your pond will get pretty dirty, so keep lots of plant material in it to help keep it clean. They will eat it, but depending on their size, maybe it will grow faster than they can eat it. You need a filter system to keep the pond clear - at least a little clear.

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.
