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

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

I already use this product but the quantity is what I appreciate

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.

Great product and excellent price

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

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

This product helps Koi get used to our large pond.

We have used this product for many years. I think my fish like it

awesome

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
