hmmm, after looking at it closely, I think I understand how this works...
feed the skimmer with a small pump from your tank... or overflow in this case...
the two maxijets grab the water from the bottom, suck up some air thru the hose you have dialed into your pvc intake pipe somehow...
the modified maxijet impeller churns the crap outta the water and air to make tiny bubbles...
all makes sense now.
Got 1 question tho...
If you flipped the maxijets return and intake, would it increase the efficiency of the skimmer?
