I am afraid that may sound good, but there is a problem with it. If there was an air/water interface all the bubbles would disappear before reaching the surface. There is a serious flaw in that argument.

And now that I see that there is agitation within the skimmer so theoretically oxygen gets taken up, I am bothered by another thing. How about the oxygen depletion caused by beating the crap out of the water with an impeller causing the bubbles in the first place
I just cannot see how there would be in increase in oxygen content.
