OK I have a Stand that is 72x24 and there is a tank that is 60x18 on it. I found a Deal for a 72x24x24 tank but Im not sure if my stand wil support the tank. On all 4 corners i have 4x4's and then in the middle i have 2 2x4's with 2x4 running across the length of the tank on both sides and cross braced on the bottom with a 1/4 inch plywood on top of the 2x4's. Ill post pics tonight. But i was just curious if anyone might think it will support a 180 gallon tank. I can sit on the stand and have the tank on it filled with water and it doesnt bend or make noise. (i weigh 230 lbs)
