i dont fully follow, are you saying that all the o2 that the skimmer sucks in with the air usually gets bound to the organic compounds and doesn't end up entering the system at all?

No a skimmer should put a potion of O2 back into the tank, this is the reason you want a bubble trap after your skimmer to break up any micro bubbles that make it threw you skimmer. Bubble = air pocket, popped air pocket = O2 into water column.

oh yeah of course that makes sense. so what about CO2? i understand it can lower ph if it gets too high, does a skimmer help reduce this, or is the only option for CO2 removal surface exchange. and how much does macro-algae in fuge help with this?

Best way to remove co2 is by water agitation, surface movement, sump water falls and so on. Any thing to churn up the water helps remove co2.

allright, ill write that down, now how do you keep it quiet? the sump waterfalls that is.

Sump drop don't have to be big to be affective. If you look at my sump on my 165 each baffle is only 1" lower the the previous.
