RS, welcome to Pond Boss. My condolences. I've never had any luck with Bentonite and have tried it either 5 or 6 times. As much as it hurts, I think the best bet is to drain it, let the bottom dry enough to get equipment in and put down a 2 ft layer of clay. Pack it with a sheepsfoot roller and not a dozer. Dozers don't pack anything very well.

I think if you do this, you'll be able to sleep nights.

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.

Without a sense of urgency, Nothing ever gets done.

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