Microbubbles in a Biocube 29

So, since the inception of my new skimmer, I have a flurry of microbubbles. The skimmer is in chamber one. Right now chamber two is a mixture of bioballs and lr rubble (in the process of making a mini fuge). Chamber three has a Rio return pump and the filter floss type pad that came with the tank. Oh, and I also put a media bag, not sure of the micron size, at the overflow of chamber one into chamber two. Any ideas as to what else I can do to get rid of these bubbles?

 

is it the oceanic skimmer?

on the left hand side, where is the water level at?

 

No, it's the aquatic life internal mini skimmer. The level on the left side is above the max line. I had to raise the level in order for the intake on the skimmer to get water. If I lower the level to in between the max and min, then the skimmer won't work.
