Crazy idea for a glass tank

[rodger]

I have an opportunity to pick up 2 240 gal glass tanks for a song. These are not ordinary tanks either. They were in a commercial display at a McDonalds, so needed to be stout enough for little kids to beat on them. Listen to these specs. 2" thick bottoms, 3/4" sides. 1 1/2" tops. Here is my crazy idea: Cut them apart. Take the 2 bottoms and silicone them together on plywood. Cut 2 of the sides down to 4" and assemble. Now I have a 6X4 ft tank that weighs 1000 lbs. The tops I think would be useless as support, so I would have to design something for top support. Do you guys think the 2 piece siliconed bottom would work if it is attached to plywood? If they would theoretically hold, any suggestions for top bracing?
Thanks

Not crazy. You could eliminate the bottom glass's and just silicone the side glass to a plywood bottom. It would save a ton of weight. You be doing what this guy did using two glass tanks to build one.

He gave me the idea for a 30" tall 145g cube made from two 70 X-Tall tanks. Its a project i am currently working on.
