Nope, being a college student you learn not to reference just anything you find online but only scholarly articles/citations. With respect to aquariums unfortunately there aren't a lot of scholarly publications. That being said I still do research online and in magazines but much of my information just comes from basic understanding of physics, chemistry and fish care. With respect to my statement that oxygen from bubbles will directly dissolve into water I'll direct you to a similar invention in the fish industry...the CO2 injection system. These systems use a slower rate of bubble and often use a track that the bubble travels along for awhile before being released to the surface. The purpose of this is not to aggitate the surface but to allow CO2 to dissolve into the water from the bubble directly. You have to understand that the surface of your tank is just a big surface of a bubble (that bubble being the outside world). If you agree that oxygen gets dissolved there then you must agree oxygen gets dissolved from a bubble at greater depths. I personally use live plants alone as my oxygen source and i'm pretty sure they don't agitate the surface (unless they are partyin while i'm in bed, lol).
