It's been talked about a few times. I think it was mentioned once that doing them ultra-real would make the whole thing eat more resources.

It would be totally cool. But the thing is that in my old saltwater tank I had power heads, and undergravel filter, and a canister with a filtered scooping end on it. None of them really made all that many bubbles. So for pure realism for that set up, turning them off may be the way to go

Personally I like to watch them racing up - real or not they are sort of calming when I am hyped up about something.
