I got one from Aqueon with 3mm thick glass that are sealed at the corners, with a plastic frame on the top and bottom perimeter. Since the bottom glass is nestled on the frame, it's a bit elevated from the stand the tank sits on, so I'm concerned that center part is gonna bend down and crack with too much weight. Right now I got about 2 in. of sand and 2 big rocks. I'm going to remove some sand to add more smaller rocks, but don't know how much it'll handle. I'm estimating the rocks will weigh around 10 lbs with possibly more rocks being added. I'll be putting most of that weight on the sides/corners, so not much on the center.
So far I'm thinking of getting some foam pads to shove underneath to help counter the weight a bit.
