Where to drill a tank

[shookbrad]

I have a 75 Gallon Glass and 2 35 Gallon Glass Show aquariums that I would like to get drilled for the overflow.
My question is where do I need to get the tanks drilled at. I do not wand to drill in the wrong place and weeken the aquarium causing a disaster.
Thanks,
Brad

The bottom would be the best place but those tanks might already have tempered glass on the bottom.

What does tempered glass on the bottom have to do with drilling a tank?
If I have the bottom drilled does it matter if it is in the corner or not.

If it's tempered glass it will explode on you while drilling... .Location of holes if untempered really depends on your design and setup of your overflow

I have my overflow in the center of the tank about 6" off the back wall..That way I can use all 4 sides of the overflow giving me more overflow area...a center overflow on the back wall will give you more area then a corner overflow (if thier the same size, ie 6x6, 7x7)
