Just for reference for this discussion I am running a Gast 1023 rotary vane pump max flo 10cfm into three diffuser bases with double 9" Matala diffusers in a three acre pond with the diffusers in a crescent pattern following the deepest part of the pond around the dam. The pump is also running two single diffusers in my sediment and forage ponds so the pump output is divided between 8, 9" membrane diffusers but only 6 are in the main 3 acre pond. I have the flow set pretty low to those two very small ponds (1/10th and 1/20th acre respectively).

I might be getting around 8 cfm in the main 3 acre pond split between the 6 diffuser heads. They are at about a 9' depth plus or minus a foot at the bottom of the pond. Right now running about 19 or 20 hours a day being shut off around mid day.

I'm pretty sure I don't know what I am doing. But that rarely stops me anyway.
