Mark, I have an out-of-state friend that has drilled hundreds of tanks. I could give you his number if you like. I believe you need to have a drill press, a diamond hole saw bit and your glass cannot be tempered or it will shatter.

I think it cost me about $20 per hole. If this is a smaller tank with thin glass you might want to think twice about it. My son-in-law had them do a 80 gallon and it wouldn't hold and broke the whole back of the tank. My 150 has been fine for the last 3 years though.

And if so, do you still have the special hole saw bit... and of course I was wondering what size it is and if I can borrow it. I've got some tanks I am interested in drilling!
