Frequent buy
Again, another item purchased frequently for the pond. It works and stores well. No issues with cloudiness or color of product/water after application. The fish seem to respond well to it. Easy to use and store.

THE emergency item you want to have handy if you leave the water running in your koi pond.
Besides a little in my aquarium water changes, I use it for koi pond emergencies. The first time I accidentally left the water running in the pond, almost all my fish died. The second time it happened, I immediately dumped stress coat in and didn't lose any fish. I think of this stuff as a "fire extinguisher" for pond water screwups. (And yes, now I use timers.) FYI - my water has chlorine in it, that's why I need this.
