David, Lusk once posted on why oakis bad news in some areas and no problem in others. I don't remember the technicalities but in North Texas it is real bad. Like all water issues, it has everything to do with soil types.
Or like Brettski says, you can take a bucket of the pond water, toss in a chunk of fresh oak wood and wait a week or so. If it starts discoloring or turning sorta black, save your money and don't bother stocking. Lots easier to burn the wood now and use rocks for structure.
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
