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

the item came damaged and leaking ---and Amazon refused to take action. Now I have to reorder it again despite the fact I needed it for today. Very unhappy

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

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

Great product at a great price. I treat City Chlorinated water for my 8000 gallon fish pond. Works perfectly.

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.

We’re faithful users of this product in our koi pond

Came as expected..no issues.i use it everyone I change water or add fish.

Nice and neat. Thanks

Works great!

My fish says she approves. Two scales up
