Honestly, I am a reading nut case and never stop reading everything I can get my hands on about this hobby. I have never heard of oxygen being directly added to the water. I have always run covered tanks, and the key is good water movement.
If you have a sump, there is a ton of gas exchange taking place. If you don't have a sump, a hang on skimmer goes a long way to providing an oxygen enriched environment, and a power head directed at the water surface will break up any oils. Ideally a surface skimmer would be used in conjunction with the hang on skimmer to eliminate these oils.
