bought a GAST oilless diaphragm unit model # doa-p101-aa
Dont know much about its specs and what it pushes.

specs HP 1/8 60 cycle max psi 60:confused: wide open it pushes 1.1 cfm

My questions are How many air stones can it run at an average depth of 20"?
second question 60 psi will I need to bleed off air if only running like 20 airstones?
I have never setup or used and large pumps before but do have it mounted 30 ft of 1" pvc conected to it with my 20 saddle valves in place and the air filter made.
kinda want to know what it will do as I am moveing my fish room over to the other side of the basement and need to deside on my tank placement and what tanks I will switch over to air.

ANY advise is welcome
Thanks everyone
Eric

Have it running and it seems very hot the case is like 150-170 degres F.
And yes I'm bleeding off lots of unused air have 5 valves wide open plus 12 air stones wide open.
