What would be the best way to set up a 135 gal (72" x 18" x 24") tank for an exterior overflow box and sump? What kind of overflow box should I purchase, and where should it be positioned precisely? With some practice glass pieces, I'm sure I could drill some holes in glass, but I have no idea where the ideal location would be.
This is the style tank I'm of getting
