We are looking to instal an aeration/fountain system to not only add oxygen and decrease the need for additives for algae, but to add ascetics to the neighborhood. Lights are definitely required. He is our issue on choosing which system would be best. Our pond currently has different elevations. We walked the pond to measure the depth and it went from about 2-3 feet around the edge to possibly 6-8 ft in what we would call the center. The pond is probably close to 15 yards across. Would a 1/2 hp aerator be enough, and which one would you suggest. Also can we leave the system in place over the winter, just turning off the electrical supply?
