125 gal drilled overflows

[Mugster]

Canadaboy, my 180 is drilled at both ends with dual overflows. My overflow is 1.5" and the return is 1". I'm currently using the Mag12 for my return but I am seriously considering moving up to a more powerful model. The return pressure is sufficient for now but greater return flow pressure would be better. My sump is a 55 gal long which sits under the tank in the stand quite nicely. Hope this helps.
