Stand pics/examples?

[Aquattro]

From a thread on RC, spanning 6 feet with a 2x6 won't require a vertical support mid span. So my design is a top rail of 2x6 on 2x4 verticals (2 each corner) plus additional support on the outside corners, as I'm making the stand longer than the tank. Then sheathing with 1/2" plywood, so strength should be fine. Not crazy about 6 inches on top, since it will block access to the skimmer cup a bit, but not a huge deal.
