I need to make a simple temporary stand for 270g acrylic tank (6x3x2). I'm thinking of just building a 2x6 or 4x4 frame, with 3 cross members and 3/4" plywood on top. The frame will sit directly on the floor. My overflows are near the top of the tank so i'm just going to place the wet/dry directly behind the tank on the floor. Anyone see any problems with this? My only worry is that i may have to shim the stand to level the tank and i'm not sure if a simple frame like this will twist and cause stress on the seams of the tank.
