I have a 120 Hagen tank. It's glass tank and it is 1/2 inch thick glass. Easy to drill? [img]images/smiles/icon_eek.gif[/img] I'm really kind of worried. I'm not sure if I should just try to get it drilled or if I should try and make a siphon overflow box. How much do you think it would cost to get a side replaced (18W x 24H) or half inch glass? I will just get the side drilled, that way if it breaks, I wouldn't have to replace as much glass as if I were to try and drill the back pane. Thanks guys. Unless one of you Victoria guys know's how to build a really good siphon overflow box...?
