We use this product in our pond to protect our pond fish from disease & baceria that causes problems. Our local pond store recommended this product to us. It's not always available & is costly but very worth having if you have pond fish. We have lost fish to ick & other diseases. Since starting this product we have not lost a fish yet!

Pros: Easy to add to pond water. Prevents fish diseases.

Cons: Costly.

I bought a fish at a WalMart that must have been infected with some kind of disease, and all my goldfish ended up getting it as well. I bought this product on the recommendation of a Petsmart employee and it worked like a charm!

Pros: It worked like a charm for me

Cons: None that I could tell
