I add water to my 5,000 gallon pond on a weekly basis. Mostly due to evaporation from my waterfall. I only use API Stress Coat in my pond.

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

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.

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

Porkchop my 10 yr old red parrot head cichlid approves. I’ve been using stress cold for several years now and it does a great job providing a slime coat for the fish and declare and eyes in the water for instant use. Highly recommend

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

My fish says she approves. Two scales up
