Add this to all my water changes and it keeps fish healthy, happy and clears the water fast. I treat my fish like they are real pets.
Stress Zyme is essential for a healthy tank, especially for breeding. I do not want to add a supplemental slime coat when fish are healthy, and this product provides essential bacteria without also adding a slime coat.
I use this is all of my tanks, and recommend it to everyone that I give my young fish to. I highly recommend Stress Zyme.

I began using Stress Zyme when using Stress Coat. Honestly, I don't know what I expected, since this came as a recommendation from some trusted guys at the local fish shop. Ever since, my aquarium water has stopped smelling "fishy", except when a freshwater clam dies. I'm quite happy with the result.
this works great. i ran out of stress zyme during a water change once and my water got really murky and filthy looking! i ordered 64 oz of stress zyme after that! great to use with stress coat! definitely recommend this!

Along w/ Stress Coat, I use them in the spring water and tapwater, for every 20% weekly water change in all of my F/W tanks. Also use them both in the water bowls for my PDFs and their tads.
