I saw this tank at an LFS that I am just crazy about, unfortunately I couldn't stay long to get a good grasp of the whole thing. I'm hoping maybe someone here has seen or built one before and can give me an idea of what is done to create this and make the whole setup work. It is a VERY large...

I am planning a 4'x4'x2' acrylic cube with center overflow. I want to have this reef setup to be viewed from 4 sides.Any watch-outs? especially with regards to: waterflow and floor support.
