I would let it sit for awhile to see what happens. Do a PH and alkalinity reading before stocking. I don't know a lot about Northern ponds so will let others advise on minnow stocking in colder waters.

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
