I haven't undertaken this project yet, but my plans to build a plywood aquarium include braced corner seams which are made of coved
2X or 4X lumber. This should in theory drastically reduce the ocurrence of leaks at the corner seams, and would also eliminate the
rectangular inside corners. I also thought about putting brass angle "irons" on the outside corners, inlet so that they sit flush with the
exterior surface of the plywood, and attached with brass screws. The whole setup would be VERY strong and classy-looking.
