That was the original plan, but there is a secondary layer of tinted glass silconed to the back. We had to cut the tank apart to move it out of the seller's basement. The we had to clean the panels and when we did, water seeped between the layers. You can see the evaporated water between the panel now (horrible when the oights are on), and it would be much to risky to try to cut off the tinted glass now. Plus it was awful to cut the glass apart when dismantling the tank, and we only has an inch to cut through. The back glass is seven feet wide and 30" tall. It would be a huge feat to get it apart back there. So... we decided to make a background for the inside instead.
