High Flyer thanks for the response and as far as the buildings go the closest one is a Chicken Coop and the other is the Barn which does have power (about 300-400 feet away). The Tilapia idea came from this forum and I picked them up at Wilner Fish Farms (Great business!). I plan on putting them in every year until I get this under control.

Do you have any suggestions on which aeration system to go with that is most economical for a 1/4 acre pond as I have already spent $1800 on that windmill system (Newbie Mistake).
