Not that I'm disagreeing with you, but, ... Actually what I was thinking about had more to do with sump size versus turnover, not the "snuff of your plumbing" or your water level, or even the velocity of each individual return
If you have a smaller sump, like, say, something that fits in your tank AND gives you enough room for pumps, other equipment, etc., you may just find yourself in a situation where the flow through the baffles is still so fast that bubbles can't clear by the time they hit the pump inlet. Thus --> microbubbles. A higher sump level MIGHT help in this case, but, you still want the level to be low enough so as not to overflow the sump in a power-off situation.
