You can get a glass tank that's 144"x37 1/2"x36" at Glasscages for $3450.00. It would be heavy as hell, but it's a great price. I got turned off by Tru-Vu tanks a couple years ago by the way they ship them. I had 2 180gal. tanks that were drop shipped to me from the company, and both were busted because they were only covered by cardboard on a pallet. If they had been crated properly, they would never have been damaged.
Yep. They shipped 2 from the factory, and both were cracked. Well, one was cracked, the other was smashed! I called them to inquire about the way they were shipped in flimsy cardboard, and Tru-Vu's reply was "We ship them that way all the time and never have a problem". The seller filed a claim, and I got my money back, but it was a bad experience. The tanks were 1/2" thick.
