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

Great product and great service

I have used this for years and works great when adding water to the aquariums.

I’ve used this product for years every time I add or change out water. Never a problem with my koi. They’re more active after use.

Helped my fish after death of two

awesome

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.

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

Have used this product for a while and recommend. Good price.

GREAT PRODUCT!

This product helps Koi get used to our large pond.
