I have been reading this thread with great interst. I have had the idea of
placing eggcrate or something similar in the bottom of the tank and placing
a couple of the 7.5w heaters under it (not resting on the glass). I have
thought this would possibly work better than a UGH not to emntion the fact
it would eliminate the unsitely lift tubes.

My thought was that by heating the water under the substrate it would rise
through the substrate drawing cooler water down into the lower water
chamber. In theory it should work much like heating cables.

Does anyone have any comments about this concept, good or bad and has anyone
tried it yet?
