Well the guy I had lined up to come and drill my tank has not worked out so it is looking like I will have to do it myself. One of the local glass shops has offered to loan me their drill and bits that I need. My question is if I have say 3/4" bulkheads do I use a 3/4" bit or do you have to go a bit bigger to accomodate getting the bulkhead to go in? I have to drill 10 holes total for my closed loop and it just about makes my knees buckle when I think about it. If you see me advertizing for a 190g plus tank in the next couple of weeks you will know that I messed up bad!
