Its in the back right corner through one of the bulkhead holes contained inside the overflow box. The crack goes to the outside edge of the tank but the side panes are intact. I guess I could use it as a tank without an overflow, or I could drill the back for a gl*******s overflow kit.
The first time I called GC they said I could use the tank as a reptile tank, I called back today and GC said I may be able to silicone on a new piece of Glass with the same dimensions as the inside of the overflow box. I would place this piece of glass in the overflow on the bottom. What do you guys think?
