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

This product helps Koi get used to our large pond.

This is all I have ever used in my aquariums.It works.Ive purchased many things from amazon also but when I saw 2 for $32.99 jumped on it but should have checked before hitting that buy button it jumped up to $43.99 & next time before buying anything here will check before hitting the buy button purchasing.

Great deal and long shelf life

Great!

Although my inexpensive goldfish did not cost very much when purchased as tiny minnows at the pet store, now they are 9 inches in length, a wonderful golden-orange color, playful and always eager to be fed. I add the Stress Coat whenever Im adding water to the pond from our garden hose connected to the local utility. I highly recommend this product.

Use this product for outside koi pond and aquarium Love it keeps fish healthy

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

Criminal activity here. Sending half-sized bottle twice, while charging for full size.

Great Value. Petsmart stopped carrying it

Works great!
