We have used this product in our pond. One summer our fish had various health trouble due to the very hot temps of the water & air. This helped when added to the pond water. It didn't get rid of everything but helped. I think maybe we didn't catch the problem in time when we did use this product. We now keep it on hand in case we need it. Pond owners that have fish will benefit from this product & it's safe for you pond plants.

Pros: Easy to add.

Cons: Figuring out how much to add.
