KoiWorx Defoamer - 32oz- Removes Foam from Decorative and Ornamental Ponds, Safe for Koi

The stuff works great , overnight the foam was gone out of my koi pond

No more foam. I use a spray bottle to distribute it on the foam

Does what the label says

This product clears up foam immediately but it's not a long lasting fix. You have to put it in regularly. Fish and plants are not effected. I gave a four star because I'm putting it in every day right now. It's super easy to use, Just measure and pour. And enjoy clear water.

I was pleasantly surprised with how quickly this stuff works, and with how much less I need to use than is indicated on the label. It is an incredible value. My pond started to accumulate little patches of foam on the surface, originating from the waterfall feature. In a rainstorm the pond resembled a cartoonish version of a washing machine that has had too much soap put in. No joke. For that, I bought this defoamer to give it a try. I followed the instructions and within a minute or two, the foam was totally gone. Like,...gone, man!Now, when I see the occasional persistent patch of foam, I simply toss a small amount, like 1/8 cup, onto the waterfall, and within a few minutes those foam patches are gone.There are very few miracle-y products out there. Most are snake oil.You only need to go to the extremes of following the label instructions if things a dire. If not, then as the saying goes, a dab'll do ya.

We have a fountain that holds 6.5 gallons of water. After we set it up and ran it for about 5 days, I noticed the water starting to get foamy. I ordered this stuff and it got here so fast I couldn't believe it. I added 1 cap full and the water cleared up immediately. This stuff really works.

product works great, except for the bottle itself needs to be redone. The cap will lock on you and you literally have to cut into the bottle to get the cap off. This is the second time it’s happened.

We have a 400 gallon water feature consisting of a small upper pool connected to a much larger lower pool via a decorative waterfall. We keep the pond clean but it can develop a fair amount of surface foam, especially immediately after having topped off the water level with the garden hose. Once formed, the foam persists, really until the pond is drained and refilled.I was skeptical about this product initially, primarily owing to my previous disappointing results with hot tub de-foamers, but I didn't figure I had anything to lose. My fears were unfounded! This product works almost unbelievably well! I pour in about an ounce near the pump inlet, and five minutes later there is not a trace of foam on the pond! How? It's like magic. I believe the package recommends reapplying weekly, but I only actually re-apply when more foam appears, and that can take weeks in our particular pond. I'm very impressed with this product and would definitely recommend it to anyone with a foam problem! In fact, the reason I happen to be here today to write a review is because I'm ordering a new jug of this stuff. Works great!
