Is this safe to use in a koi pond?

The only problem would be the Koi Disco dancing all night while the light is on...

But no I don't think there would be any real problems...so yes it would be safe.

our pond holds 10,000 gal of water. We purchased the Laguna pump sized for the volume of water in our pond. This is important to have the correct size for proper aeration for volume of water. Too little will cause dead zones in your pond, and too much will cause the water to be too turbulent in the winter months. The koi fish need to rest on the bottom (quiet time) during the winter months. No problems with the pump at all this winter despite how cold it has been. Pump never missed a beat during -35 temps. Now the hard part is waiting for the 18 inches of ice to melt to see how and if our fish survived. Julie our pond holds 10,000 gal of water.

It is natural bacteria that is not suppose top be harmful to fish plants or animals and I have been using it for 3 years and my KOI, Goldfish, frogs and plants have not had any problem with it. I do not have Trapdoors but I would assume that they should be alright with it.

It easily aerated my 250+ gallon pond for my koi fish pond. Just remember to turn it off after dark.

i use mine on my hot tub.. with all the curves and angles it works very well. i dont see why you could not use it on your pond/fountain as long as you dont suck up any fish that you might have in it . :) the catch bag is easy to clean out after every use.. i am very happy with mine .

I don't use it -- there is enough biological filtration happening in the pond. Just like in fresh water tank, the lava rock is just there to give a place for bacteria to live. I've seen no issues not using it -- fish and plants ( and frogs ) were healthy. :)

No, it doesn't hurt any fish. Just clears the water with regular use. I've used for years with no ill effects!!

It is not submersible. Run flexible hose underground to the site you have the filter in. We have ours behind one pond's walls(koi), and in-the-ground on the other pond. You may want to use an algecide to speed up the balancing. We love both ours. The Koi pond requires a flush every 3 days or so. The guppy pond get less sunlight and does not require flushing.

I don't have a personal experience using it under water and for a fish pond. According to the Thermabond web site it will probably work as long as you clean off the algie really well. They don't guarantee it, though. I suggest you read the instructions on their website about cleaning the surface and squeezing the water out from between the tape and the surface. In the reviews on Amazon for Thermabond kgraham used it for a koy pond with success. Didn't say anything about the long term effects on the koy.

Yes, I have this in my Lowes 200 gal. kidney shaped pond. I live in Florida. This is a very high maintenance item. I am constantly clearing the pump and cleaning the tank. It works.

I can block it with my thumb too. Not sure how to answer this question. All I can tell you is that this is the best pump I have ever bought for my koi. They love it and the pump lasted outside (covered of course from sun and rain) about 7 years. My fish fricking love it! When I turn it off to clean the filter they all go down to the bottom and just lay there. But as soon as I turn it back on, it's like club koi again. They dive all through it and let it lift them to the surface (so cute). And these are like 15lb koi. And it's been nice for this artic freeze b/c it keeps the water from freezing.

I believe so. It works great in our yard at my koi pond, quirrels and small birds also set it off. It also keeps our dog from drinking pond water.

I use it in a plastic bird bath with no problem. A couple things to be aware of - it works well down to 25 degrees or so; also it would not keep a large area of water ice free and might not be good for a pond deeper than a bird bath. Around 25 it would clear a small area around the unit. It will ice over in the zero to 15 degree range. To work at those low temps would take a lot of current and might damage bath/pond material.

I do not know about koi fish. check with the manufacturer to determine this.

I run this in an aquaponics system (plants and fish) No issues for a year+. I think we're safe

The product says it's safe for plants and fish. I use it in my pond which has both plants and fish and I treat my pond twice a year just to be on the safe side. I haven't lost any plants or fish due to the use of this product. Hope this answers your question.

we used it last year, and we swam in it with our grandchildren and there was no problem. All of our fish are doing well too, even through the hard winter we had here in Ohio. The product cleaned up our pond really well, with no side effects on us, the fish or the plant life we have planted around our pond.
