ok i just didnt know if you could unleash the full potential, i assumed i needed them all open, but that is great news and thanks. What if i was going with a DWI Boss Hog airstone. Just attach it to one and close the remainder?

 

[akito]

YES That one ^^^^^

diaphragm pumps are much quieter than piston pumps, but do not last as long nor deliver the same PSI consistently when there is significant back pressure
but they are quiet and you can replace the diaphragm when they wear out.
