Well,I tried and I tried and the micro bubbles win.
First design:both 1" drain lines into 1 1/2" pipe into 4" tower.By trial and error I varied height of water brake,drilled several vent holes,drilled additional holes below water line.All attempts produced micro bubbles.NG!
Second design:each drain line to have separate tower.Did same modifications as first design. NG!
I even tried a seperate one for the protien skimmer.NG!

All 3 failed bubble towers

Final outcome

Unless I find a different design, back to the 'eFFin' filter sock.
