Freg, is it legal to stock tilapia where you are? They won't survive your winter temps, but do a good job with algae. You'd probably only need a few for a 1/8 acre pond. Stock mixed sexes when water temps are reliably above mid fifties, they will eat algae & spawn more until water cools down in fall.
