"I love this product!! It is so good for fish! No heavy breathing nor stressing if you follow directions as it is."

"Directions State - Allows Safe Immediate Introduction of Livestock. I Added Fritz Zyme to a new aquarium fallowing directions. After 2 hours ammonia and nitrite were still to high to add fish. This possibly due to Fedex delivering a day late and allowing the bottle to freeze."
