In the process of setting up my 200g reef I decided to drill a couple holes in my 56g refugium. I used the diamond dremel bits and it was much easier than I thought. The bits were around $9 each and it took one to the the holes started and a second to finish them so for less than $20 I got two holes.
If anybody has been contemplating this but is afraid, don't be. As long as you have a partner to spray water keeping it cool and go slow allowing the bit to do the cutting you'll have no problems. I do belive my tank was 1/4" glass becasue it was a bit taller than normal tanks so drillinga smaller tank would be a little toughter but I'm going to try this week on my 30g, and another hole in the back of my 200 and fix a crack in my 150g.
