Best return config with a Mag 18

[MNoel]

I have a mag 18 return pump for my sump and I'm trying to decide to go with 2 return outlets by placing one in each corner or if I should build a spraybar to go across the back. My tank is a 6' 125g without any drilled holes. I have 2 hob overflow boxes. Trying to get the best circulation out of the return as I can. Any advice will be greatly appreciated.

Thats a toughie! I would go with the two corners, and something like a seaswirl if you can afford it. You will prolly want to add another closed loop to hit any dead spots!

A mag 18 is a good pump, but does put out a bit of heat. If it were mine and new, I'd trade it for an external pump.
