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

always good quality, this is something you can trust on the koi fish pond.

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!

Did the job!!

My fish says she approves. Two scales up

I have used stress coat for years and never had any issues with this product. It works great for those larger water changes or small ones.

Great!

Cant beat the price. Use it for every water change. Good stuff!

This product helps Koi get used to our large 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.

Product arrived quickly and is as described. Good price too.
