problem with protien skimmer

[zabadoo]

I'm new to saltwater tanks. In Oct. 05, I had a 125 tank installed. Everything is fine so far except the protien skimmer. For some reason, I cannot stop the fine bubbles spewing out of the top of tank where the water retruns after the pump pushes it up through the cycle.
I have also tried adjusting the air flow into the protien skimmer but it does not work. Any suggestions for me... thanks

adjust the intake of water. I have a similar problem and the cause is my pump for the skimmer is to powerful and pumps water faster than it can handle. so I minimize how much water it sucks in.
