Best Drain/Return Setup for my New 130gal

[DJ Monty]

I'm just about to set up a 130 rimless with a rear center overflow box. The tank has 3 1" holes drilled. What would be the best drain/return setup to use ?

If all 3 of your holes are in the overflow box, that is the way to go. Of course, you will need to either drill returns elsewhere, or use over the top returns.
