That is cool. I've always wondered about doing something like that except I was thinking of having it horizontal instead of vertical. (Seen some displays at public aquariums like that.)
If you could find an appropriate timer control, wouldn't it be awesome to have 2 pairs of powerheads, a pair on each side, and have them alternate every 20-30 seconds? A wavemaker might work as long as you could try various settings to find the optimal setting because I assume it takes a few seconds for the water speed to ramp up, and it would be worse if it had to change directions on top of that. But imagine how amazing that would be ...
