API POND STRESS COAT Pond Water Conditioner 1-Gallon Bottle

Great stuff. Works great in koi ponds and aquariums.

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

I love my Koi. I love my pond. But am I going to set aside large quantities of water to replace a percentage of my pond water when I backflush? Uhhh no! So my Koi enjoy a rainlike experience when I use a sprinkler to both replace pond water and water my landscape. The sprinkler helps get rid of some chlorine and Pondcare Stress Coat takes the worries out if I dont get rid of all the nasty stuff. Hey and the Koi get some spa treatment with the other stress coat benefits. Happy Koi, Happy Owner..er Caretaker

Makes them perky and active. I actually think they look forward to the weekly treatments I give them. Ive about 800 gallons so using a cup a week makes a gallon last for a loong time.

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

excellent product better than expected very good quality and fast shipping

Keeps my pond safe for my Koi after water additions

Like it cute my fish

When we first built our pond, we were noticing our fish getting sores on their bodies. Several fish ended up dying. Stress Coat was recommended and I have been very pleased with the results. Every time I add water to the pond I add some Stress Coat according to package directions. I really notice the improved health with my fish. I only need to use Algae Fix and Stress Coat in the pond to keep it clean and clear. Both must be working since my fish seem to be thriving.

as expected
