I was reading several posts about using an air pump with this skimmer. I have this skimmer and tried to hook an air pump into the the air injector. All this does is stall the pump, and it pumps no water. Anyone that has done this please let me know how you did it without stopping the pump. I even cut the air flow down, and it only works at a trickle, which is basicaly no more than what it was drawing on its own, without the pump.
