Hi all, I know there are many threads similar but didn't find one similar to what I wanted to do. I want to create a stand for a rimless 72"x24"x24" tank that is 19mm thick. I wanted to have a clean open look and not have a brace in the center of the stand. I was thinking of using 4x4 posts (four on the left and right) and then sitting four 4x4 posts running horizontally on them and then having 3/4" plywood on top. Sort of a bench furniture style. Is that enough to support the weight of the tank that is roughly 165gallons? Or should four 2x6s be used instead of the 4x4s for the horizontal beams?
