Title: A MUST HAVE!
Review: This product has saved the lives of many fish. I have had a hard time getting control of the water in my tank. I used two cap-fulls in 20 gallons for weeks when my nitrite and ammonia levels were off the charts. It saved my only remaining fish. I didn't discover this product until most of the fish were dead. Now I use this regularly for water changes and when there are problems in the tank. It is hands down the best product out there.
