Well worth the money. Highly recommended.
This actually works!! I was using Pondworx for years but this way better at keeping the water clear as well as eating up all the debris. I have .75 acre pond which is up to 20ft deep and one gallon of this made a noticeable difference within days. Using once a month now and even though the water is up to 85 degrees is nice and clear. I do use two large bubblers as well to keep the water moving. Yes it’s slightly more expensive but well worth it! 😁

Great product
I haveca small backyard pond that was really murky and dark. I've tried a bunch of other products- more expensive ones and this one worked the best. It cleared it up w/i a day and has stayed clear for a week now w/o being retreated. I only used 1 cup and bought the gallon so it will last for a long time. Koi had no reaction to it and pond is crystal clear! Good stuff!

Doesn’t work
If I could give this zero I would. Absolutely nothing happened at all. The algae is worse than ever.

Maybe it works?
I think it is helping to clear the water but I don't see the muck getting better. I will stay with it to give it a fair chance. I say it is helping with clarity because I have a lot more weeds. I assume that's from increased sunlight

Works good but use as directed.
This does work but it does take time. We have been using it for about two years now and we have noticed the difference. Also it’s imperative to use the proper amount - don’t skimp and use it monthly as directed. Safe to use. Fish are thriving. Our dog swims in the pond and hasn’t had any ill effects.

Perfect Pond Cleaner
This is perfect for our community pond. I tried using the pellets however they didn’t work very well. This is perfect , clears the pond water and doesn’t harm fish. Definitely will return for more in the future.
