I will never again put freshly dead oaks into a pond. I did it and poisoned my water for a couple of years. I finally pumped it dry. That's a huge thing in arid North Texas.
Try something. Cut a piece of the oak and put it into a bucket of pond water. If the water turns black, don't do it.
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 Grandpa
