Drilling 60gal cube

[mibwb]

I want to drill a 60gal glass cube and put a sump under it. What size holes should I drill and where? I think a center over flow would be better as far as viewing from sides.

I'd be looking at the 700 gph Glass-Holes overflow kit. It comes with everything, including the bit to drill the glass. They are small and very well designed.

Drilling is easy. BRS does have a good video for doing it. If you can, use a drill press and use only slight pressure on the handle. I use plumbers putty to make a 3/8" pool around the area I want to drill and fill it with water. This keeps the bit cool and lubricated. Just make sure you do not have tempered glass. I also put tape on the back side of the glass where I am drilling. This keeps the drilled out piece from dropping on the glass on the other side of the tank, possibly chipping it, and it keeps the piece from spinning when the bit breaks through which will help to reduce chipping around your new hole.
Take a look at You Tube for videos also. It is kind of scary the first time you do it, knowing you are putting a hole in a several hundred dollar tank and it might crack. My first hole was in a 75 gallon tank.
Good luck

Thanks for the replies...Another question is how to truly tell it's tempered glass. Some tanks I have say tempered by a sticker on bottom. But most don't.

Using a phone, netbook, ipad, etc., and a pair of polarized sunglasses, put the phone, etc inside the tank (ideally with a white screen showing). Wearing the sunglasses, rotate the phone until it goes to black. If you see total black, it's not tempered. If you see blotches or streaks, it's tempered. Hope this helps.
