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.

How does an impeller deplete oxygen? Is it organic and has a requirement for oxygen?? Sheesh Bob, where do you come up with your ideas?

Actually a skimmer serves to oxygenate the water by producing fine bubbles that take longer to reach the surface thereby increasing the contact time with water and increasing the oxygen content of the water vs. larger bubbles which jet to the surface much faster and have a more limited contact time.
