Dan, I went to the Dept. of Health to have my well water tested for bacteria and other nasties. I sent my pond water to Texas A & M for analysis and had to get help interpreting the results. They have different specialties. I expect the NRCS or County Agent could give you some guidance.
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 Grandpa
