Pond Boss Forums AERATION Systems questions Line diameter, CFM capacity, back pressure, etc??

Journeyman makes good sense about features that slow and restrict flow. My test was using new 300ft smooth wall tubing coiled with 5cfm. Hooked it to a soft hose on the manifold on the pump which had an air gauge. I suggest you run 3/4"ID from the pump to the water line. Then connect to 5/8" weighted tubing. A 3/4hp compressor will create 10cfm and a 1hp probably 15cfm. If you are pushing 10cfm then larger diameter of 3/4" is probably better.
