WHat I do for air right now is gang about 4 Optimas into a foot
long plenum in the basement then run 4 lengths of airline tubing to 
the main plenum under the tanks. That is a big piece of ABS that had
holes drilled and solid tubing cmeneted in. Onto each of those
goes a short piece of airline tubing, then a brass valve then into
the tank.

That ought to work for CO2 as well is another was built just
for it, right? If not, it would be easier just to put them
on a common recirulating system.

30 is just what I have now. I still have the rest of my tanks
in the barn.
