API POND STRESS COAT Pond Water Conditioner 1-Gallon Bottle

This is my go to when doing larger water changes in my koi pond. The stress coating helps keep them healthy. And its cheaper to buy on Amazon than at Petco or PetSmart, so Im a happy camper.

I love the product. I order it regularly. The only concern was this time the seal on the top was broken and the stress coat leaked out into the box.

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

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

Works well.

Great value

Works great.. Will order again when I need it.

My Koi have not developed skin burns after adding new water and are lively afterwards.

I have used Stress Coat for many years in my Koi pond and it does exactly as advertised. I rely on it to keep my fish healthy.
