Pond Boss Forums AERATION Systems questions Diffuser depth?

Joe, I dont see a problem with that at all.The windmill in itself will give you varied aeration unless you have electric assist.You also perhaps have airstones or large pore membranes and the lift wont be to the point of over circulation most of the year. HOWEVER I would consider just shutting off the deep one about Thanksgiving and turn it back on the end of March or first week of April in your neck of the woods.A simple way to do this is just T in a dump valve and let the deep one exhaust off to the air when you dont want deep circulation.This is providing this mill has two independent pressure lines off the compressor.
