API POND STRESS COAT Pond Water Conditioner 1-Gallon Bottle

Been using for years, recommended. No issues.

Very fast delivery I like that

I use it with my weekly water changes in my 1800 gallon pond. Koi are doing well with it.

Its a fabulous product

Stress coat is working really well for my out door fish pond. provides an easy add way to care for them.

Works very well, either when you add water or introducing new fish or even for ill fish! Outstanding!

I have purchased this product in the past for a fairly small koi pond. It keeps the koi healthy and happy. Good product and good price.

Fish are happier...!

I can tell a marked difference in my Kois health this year since I have started using Stress Coat.

This works great for our pond. We use it for summer water exchanges and in winter for health protective slime on fish. Bummer end that I bought it through Amazon on free shipping... Product never made it.. Post office sent card that said it was damages in shipping. I contacted Amazon and reordered... But this time it cost lots to ship...something must have changed with shipping procedures. Ive had a bit of bad luck. Normally any shipment arrives perfect!
