I build all of my stands overkill. My hieght is generally a minimum of 36" tall +/- and depending on my needs. I also make the width a minimum of 24" regardless of tank size. The reason I do that is two-fold. 1. In case you upgrade to a larger tank, 24" is usually the width of a standard tank. 2. I have a ledge to put things on as well as places to do some "non-conventional" plumbing. I'll take pictures of what I men exactly.
My current stand hold a 58g and a 40g breeder. If I tore those tanks down, I could hold a standard 300g tank in need be without doing anything to the stand.
Dedex, you want to make sure the legs are braced. The tank needs to be supported around the perimeter ONLY (on glass tanks only). Do not support the bottom pane of glass on a glass tank!!!
Acrylic tanks need the entire bottom to be supported. I use 1/2" or 3/4" foam sheets cut to size, layered on top of plywood.
