Describe what you're going to do with your aquarium please.
Or build it, post pics, and stand back for a critique.
Have you grown at all before?
BTW an aquarium can be a real pain in the ass. They are fragile, develop leaks easily, can't be drilled, and aren't lightproof.
I'd go for a simple rubbermaid-tote setup like a flood-and-drain.
VERY simple and cheap to assemble.
