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! 😁 Review: 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!
