That's at the house I just moved that beautiful 150 into. Tank is really rough just FYI. It's worth it to go see the awesome 150 my cousin set up and maintains.
If its 3 ft deep like he says than it definately is a 240. its hard to tell from the pic, but it looks to be 2ft deep × 4 ft wide x 3 ft tall, which would be a 180 gallon
