bondolo said:Congrats on the tank. You probably want at least 600gph turnover for that size tank so at least 1 inch. If there are going to be lots of bends in the pipe you may want to go to 1 1/4 inch.
The place to ask, I don't know whether they drill or not, down in Cupertino would be Dolphin Pet Village in Campbell. They probably know some who can drill if they don't. You could also drill it yourself (Even I was able to do it, how hard could it be?).
