API Stress Coat Water Conditioner 64 fl.oz, Pack of 2

This product killed all my fish. I used it during water changes and it kills all the beneficial bacteria, my tank clouds up and only the hardiest of fish survive. DO NOT buy this product

We have used this product for many years. I think my fish like it

It is exactly as advertised. Because my gold fish were developing white spots, I am now adding this to my pond after adding city water to it. Dont know if the spots disappeared on their own or it was this product, but I am going to continue to use it!

its the only think what helped my pond

Now this is a product that I would purchase again for conditioning of water for my fish. Save time from running back and forth to a fish store to get a small bottle.

Helped my fish after death of two

This is the best way to buy the Stress Coat. We use it weekly for our aquarium & our grandson’s. API is the only brand we use.

GREAT PRODUCT!

Works great. The koi love it

Came as expected..no issues.i use it everyone I change water or add fish.
