Bests & Worsts Reviews from Amazon

What a disgrace to have this product bear the Tetra name! I did everything exactly like the bottle said. The label says it can be used with fish. WRONG! The next morning Six Dead Fish from the fish safe product(see picture). I was furious. In addition to the floating dead, there was an additional glow fish and my zig-zag eel that were paralyzed and a just barely moving. They are currently in the last stages of dying!. Every one please be careful if you try this product. I will be asking for a refund from Amazon and reimbursement from Tetra.
