Multiple glass pane bottomed tanks?

[zum14]

Ive wondered about this myself but came to the conclusion of not doing it. My concern is not the tank. Its the support under it. It would have to be a steel stand that would have to be rigid as heck. Do- able. Now can you keep whatever the stand is on stable? Houses move and settle all the time. Really cold day in winter shows that well when things are cracking and snapping. And even that big concrete slab in the basement is moving. Its not much, but its enough that i didnt want to take the risk. A tank like that would be show and have lots of money invested. Saying that though it has been done. Theres one on reef central where he built a large L shaped tank. Hes got more money then i do. The acrylic idea is interesting......
