That is a great alternative idea, but I couldn't trust the hangers to be strong enough for this application.. one of my rocks is in the 50lb+ range and is hopefully going to not be a base/bottom rock. I can't risk that one doin any shifting in a bare-bottom tank @_@

My tank is also just over 2' tall, and I intend to have one rock pile beyond 20" tall if I can. If I were running a shallow tank, or using lighter rocks, I would certainly give this a try. I figure I have a chance of finding somebody in Austin that might have some spare pieces, but if not, I'll just bite the bullet.

I don't plan on constructing something quite as open & large as this, but this is certainly the original inspiration: http://www.reefcentral.com/forums/sh...&postcount=811
