drilling a 75 gal

[TKByrnes]

I know that you cant drill tempered glass but... if it has a sticker on the bottom of the tank does that mean the whole tank is tempered or just the bottom? if anyone knows please help me out.

It usually means just the bottom. If it is an All Glass brand check the following link.
