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

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

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.

This product helps Koi get used to our large pond.

Fish told me they love it

Fish always do well with this product. Always add after water change. No issues.

This product is great for my goldfish--especially when adding water.

Works great. The koi love it

Great KOI Conditioner treatment

I am very happy with my purchase! I highly recommend the seller!

I already use this product but the quantity is what I appreciate
