Angie What type and brand of glass drill bit did you use. I have to drill some holes in the side of a 65 I am going to use for a fuge. Any advise you can give would be great, I have your old 65 and 30 sump all finished. It turn out really nice!! So now it's on to the 215 gal with a supper sump in the basement in all it will be round 450-500 gal. So I have a few holes that need to be drilled!
