It also depends on your location. In pine tree country, your water might need a boost. However, in oak areas you can dang sure kill a lot of fish with it. Been there, done that.
Have your water tested prior to adding anything.
It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP
