If you can increase the surface agitation caused by your filter's outflow, that should provide more than adequate oxygen to your tank.
I've always agreed with that, but I also wonder how much oxygen is actually diffused into the water from the time the bubble leaves an air stone at the bottom and when it reaches the surface.


Anyone know? I'm in research mode now
