I've started work on a stand that will support my 75 gallon (4' x 18.5" footprint), and will support a 120 or a 4' 150 (Oddball, I know, but I've seen one. Same as a 120 but 6" higher.)
Here's what I have so far:
The 75 will sit on a 2x4 laid on-edge on those slots in the 2x6s. Larger aquariums will sit on a rectangle the same size as the one around the bottom. There will be 4 more 2x4 posts between the bottom rectangle and the top rectangle so that the screws are not bearing the entire load. Given what I've read about how strong 2x4s are, I think I'll be able to park a couple SUVs on it when its done.
Next to go in: a plywood shelf for the bottom. 1/4" pine plywood. I cheaped out. I think it'll be strong enough for a canister filter though.
