Tex, adding bentonite to an existing water hole, once it's holding some water, is called "sprinkling". I've personally only heard of one successful application. I find that the best cure is to identify the source of the leak and correct the situation by applying 2 ft. of well compacted clay to that leak.

Jason, hard to tell from what you're saying. New ponds wick water back into the surrounding soils. If it's wicking, it should stop taking water (after a while).

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
