Thanks a lot for your advise, Dinky. I guess that I was applying too much
pressure. I need to be more patient even though it takes so long to drill a
hole! The tank is going to used for an external refugium and is 10
allons. -MIKE

10g's are even harder to drill consider either putting a piece of glass under the hole to
support it, or using a diamond bit for a dremel. use lots of water and take even longer.
