Well I went today to get the tank an it wasn't exactly as described lol. It looks like an older tank. Edges aren't really polished out, cheap plastic trim on top an I would trust it to hold a cup of coffee lol
The dimensions are actually 84x30 wide x 20 inches tall.
I beat them down on the price to 260 though! I'm going to cut it apart and remove the glass centre brace and have all the edges polished up. Im also going to have the back pane notched for an external overflow. I actually prefer the 20" height over the 30".
Actual capacity is about 200 gallons. Once I get it all redone it will be a really beautiful shallow reef.
