That's very interesting, what is the source on that? I don't at all mean to question the validity, but I'd just be curious to read about the effects of bubble size.

My lady is a waste water engineer and she's saying finer bubbles transfer much more oxygen to the water than coarse bubbles. She's unsure if bubble size effects water circulation to a large extent, but is saying the surface area of many bubbles is far greater than the tank's surface area for gas exchange. The issues with finer bubbles are more back pressure, increased electric costs, and loss of air volume with more stress on the pump.
She did say a waterfall like my wet/dry sump would be better. Or, an even more effective option, a propeller churning a water/air mix (I'm thinking protein skimmer setup) would be significantly better given a high enough flow rate.

It's true that finer bubbles has greater total surface area than coarser bubbles and can transfer more oxygen through the bubbles to the water. But oxygen transfer includes surface breaking which has greater area and impact than bubbles. Do a search in waste water engineering and aquaculture and you can find literature on optimum bubble size. The air stone bubbles in fish tanks look wonderful, but order of magnitude finer than those used in wastewater and aquaculture engineeing. Air stones got clogged up quickly by biofouling, creating back pressure and noise in the air pump.
