How do I drill holes in my sump?

[Keith A.]

I'm in the process of planning my new sump. I have a 20 gal high tank that I'm planning on using for my sump. I'd like to drill a couple holes in the side so the tubes coming down from my overflow box can empty into the sump. How do I do this?

Thanks,
Keith

i would skip the holes and run them right in the top, into a filter sock holder.
if you still want to drill holes in glass, you will need a diamond bit and some plumbers putty.
