My primary use for API Stress Coat+ is to maintain a healthy slime coat on my KOI. A good slime coat on KOI reduces the chance of infection from wounds and parasites. Best product I've found next to salt. Since I have water plants salt will kill the plants where Stress Coat wont.

Works great. I wish I had ordered a smaller bottle as I was still using it more than a year later. Worried about it still being ok and not toxic. Would be great for multiple large tanks or a pond.

We have Koi out doors in ponds and some babies in an aquarium. Can't live without this product. It works incredibly well. If you have a sick fish or do water changes it is remarkable. Highly recommend this.
