So I've finally gotten the information and funding to start my ~300 gal aquari-coffee-table-arium. It's going to be 90 inches long by 30 inches wide by 22 inches tall. I was going to use 3/4 inch plywood, and instead of gluing or screwing the edges, I was going to use metal angles along the edges and bolt them together. Do you guys think it will hold up without bracing?
