whew with rock and sand its at a bare minimum 400 pounds... but I was thinking about using two jackposts for support, and at 18,000lb capacity each i think they would hold it, along with two wall mounted supports. These are what I had in mind set at 5' for easiy viewing height. http://www.thegreathardwarestore.com...936&click=2744

Im planning on moving into an "urban" building where the floors are polished concrete, which I think suits this theme well. Does anyone see any problems with this idea? I could probably get away with one jackpost and 2 wall mounts too if I use a thick wood for the base under the tank.

hmm.... so much to think about. Im shooting for this to be finished around Aug. before school starts back up.
