I am starting to think about this with the pond being right around 8' right now and my shallow water diffuser out of the water. If we don't get rain this fall I am not sure what to do. Afraid there are too many fish in the pond to not aerate but not enough depth in the pond to aerate safely. Maybe I need to get Nate to bring over some folks and fish out some of me bluegills. Just haven't had the time to do it myself.
