I am mentally planning on having the front of the stand be somewhat like a octagon type shape when viewed from above. Maybe a flat door across the front for the primary access point, and two panels per each side of that. Keep the back mostly open with perhaps one-2 uprights. And the tank itself will sit on a thick piece of high-quality rock hard plywood. If I support the ply wood from below with several uprights, and finish the front with a few panels/doors, I'll be OK. I am utterly amazed at how cheap the stands are that come with many tanks these days, it is amazing to me that they hold the weight they do. I built a simple stand for a 25 gallon and I bet it is stronger than the 75 gallon stand I saw at the LFS.
