I'm using a Rio 2100 pump but I don't have a needle wheel impeller which may be part of the problem. I too am getting bubbles and I'll try the carbon bag in the box.

 you should get a needle wheel impeller it will help immensely you need as many tiny bubbles as you can get. the two black knobs are for dialing in I have mine set halfway between the outlet and the skimmer body. I find have in them point to wards the middle or each other it was a bit easer to dial in.
