Bill, the way I have it set up currently is one dual station and one single in approximately 16' of water. These two stations are on either side of the deeper area that the quad station resides in. At 16' the small pump should make 4.5CFM.
Then I have two more singles in much shallower water. One single in 6-8' and the other single in 10-12'. I feel fairly confident the small pump can run these four stations/five discs for 8-10 hours per day. That would put me at .9 CFM per disc.

Just to reiterate, none of that accounts for the Koenders windmill running a single diffuser in ~8' and the American Eagle running a dual diffuser in ~8'.
