+1, a properly built stand (using 2x4) can support a lot of weight. My tank was custom made by my friend's father to raise the tank display 38" from the ground. I only have 120 lbs. of rocks work on this tank (50lbs base, 20lbs live, and 50lbs Pukani rock which takes up 2/3 of the tank) and I am confident that it can take more if I had the room for it. I wish I took a lot more pictures of his other aquarium stand and wood work, but here are some pictures of my friend's current 2,000 gallon tank with over 900lbs of live rock.xrayjeeper83 wrote:If you properly support the bottom you dont have to worry about that.
The glass magnifies the back wall, but the tank is over 5' front to back..

His 125gallon wet/dry system to give you an idea of the depth of the tank..

Another puffer owner (8" porcupine)...
