tempered or not
I need to know how to tell if glass is tempered or not. I'm going to be drilling my 30gal soon, and well, if it's tempered, then I'm not going to drill it. Are there any tricks on figuring out if glass is tempered?
cheers

I'd doubt it is tempered. To tell put on a pair of polarized sunglasses ($10 @ walmart). When you look at tempered glass you will see ripply indention looking things. Other than that I'd bet that the sides are not tempered but there's a chance that the bottom is.

If it is tempered there is usually a sticker stating this.
