Course my pond is only 1 acre but I have used in the past for a quick fix is a nice size trolling motor. Hook it to the end of the dock put a nice size marine battery on it and set it to like 3 and let it run. You will be surprised at how much water it will move and mix. Or if you have a small gas operated boat motor that would be good too. like a 7 or 10 horse. Get that water moving and mixing! That should help!
