Tank Oxygenation

Is a skimmer enough to oxygenate a tank? or should I consider an airstone in the sump?

A skimmer and the normal agitation found in a sump is more than enough. Most gas exchange occurs at the water surface. In a sump the surface is always new you are getting premium gas exchange. Are you experiencing a problem that you would attribute to low oxygen levels?

Do not mistake the bubbles for oxygenation, the gas exchange takes place when the bubbles break the surface. There are several reasons why airstones are ill advised for the tank itself, saltcreep, seaspray and micro bubbles just being a few.

To the original question...no, there is no such animal, once it reaches saturation, onxygenation does not take place, excess oxygen is simply released into the air.

It was my understanding that the bubbles in the skimmer (being really fine) collect or attract DOC's to them selves, thus the O2 in the bubble doesn't actualy contact the water.

I kind of think of it this way. The DOC's act as insulation between the bubble and the water.

When the bubbles from the airstone break the surface, there is a fine mist of water that kinda hovers there. The water, if you have a SW tank, contains salt. As the water dries up, on the lights, hood, side of tank, ect... , the salt stays. Soon, you have a crust of dried salt everywhere. Unattractive and a real pain to clean up. If it's a FW tank, you'll usually have some white deposits where the spray has dried up.
