How difficult is it to drill a tank with a diamond edged blade? I have never seen it done, but would also like to learn what it takes to make that happen. I would not mind a DIY refugium or sump one day.

In addition, how hard would it be to drill an acrylic tank? Not a large one, I am thinking something along the lines of an Eclipse. I have 2 6s, and wouldn’t mind trying to turn on into the refugium for the other.
