Have you considered running some type of nano skimmer on the tank in order to help with aeration? Not sure what options you'd have but a small airstone driven skimmer could likley be incorporated somehow.

Yes, I have left a cm of space at the top of the tank and have the powerheads directed near the surface to help stir in more O2. I think a nano skimmer is in order when I save up more cash. The initial startup of this tank has to be paid off first. I guess I shall work out the kinks first before attempting any other livestock.
