i usually keep them about 1'' below the surface, but a powerhead operated RUGF (reverse under-gravel filter) with a good HOB or canister filter would work much better..
then again so would a non-hexagonal tank
To properly aerate or move the surface of your tank's water, the elbow of an undergravel filter should be JUST BELOW the surface of the water so the water-bubble stream that exit the elbow just skim the water's surface.
