I would like to use a standard oil less compressor to charge LP tanks for aeration of my pond. I have a 2/3 acre with 22 degree banks to 15 ft. deep. How much air do I need to turn this over? I would like to use two membrane diffusers. Which would be a better choice the flat style or round, and how large should they be. How far apart? I was using a GAST pump which ran 24/7 and it don't like the stone diffuser getting clogged. I am trying to get better efficiency by charging the tanks and regulating flow with valves. I am totally ignorant on this subject and am not sure if it even makes sense. Lot of calculating to do here to make this determination. Any insight would be greatly appreciated.
