I am cutting slots in the back of my 75 gallon for an external overflow. I know I need a diamond saw. What I don't know is what blade/tool I should use. I am planning on using a 1/2" diamond hole saw for the ends, but it's the long cuts that I'm worried about. I don't feel that a dremel would be a good choice. The cut will be about 24" long, and trying to keep it straight might be problematic.
