80x30x30

As mentioned, scratches could be a big issue so either make sure it's in good shape, or be prepared to have it professionally polished. This is not something that you can diy from what I've seen/heard. Also, as scuba mentioned, you're talking about a huge investment in equipment ley alone fish/coral. It's a good price but you'll have a long way to go money wise to get going. Of course if that's not an issue and you're experienced in reef keeping then go for it.

 

Update- I puchased a 72x24x32 tank. Its Acrylic and I am going to Washington to pick it up This weekend but won't get it home until August 12th
