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

Received the product super fast and just what I ordered.

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

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

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

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

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.

Great price and delivery was fast

Good value!

I have used this for years for my koi. Its probably the best product on the market for the cost for water replacement and start up for ponds and aquarium uses
