I'm planning a new 600 gallon tank (96 x 48 x 18) with a 10" square overflow draining from all 4 sides into a 75 gallon drilled tank as a sump. Considering either Little Giant 5.5-MDQ-SC or Iwaki MD-100RLT for a return pump. Issues will be reliability, noise, and heat. I'd welcome recommendations for these (or any other).
Thanx.
