Re: airpumps?

                 The first thing I would suggest is using PVC piping, and 
plastic valves that are available for about 25 cents each as air control 
kits. A quick drill and a valve  can be inserted.   this will provide 
individual control for every outlet.  gang vales are great but one is 
always adjusting one or the other as more filters/airstones are 
added.  Also include one more valve than needed to release any pressure.  I 
always "bleed" my system to prevent back pressure.  My pump is too large 
for your situation

                 Pumps are a total matter of preference, but a piston or 
vibrator will more than handle the number of outlets you have.
