Return Pump - in the sump or external?
Just want to get opinions from people with submersible return pumps (IE Mags) whether they have a preference for the pump to be in the sump or to be plumbed externally.
And does putting it in the sump minimize the pump "hum"?

well its going to depend on how much area you have to work with under your tank?
as for a submersible like a mag 18-24 your going to add 2-3 deg in water temp. And if you go with a external you are going to have to hve the room to put it in and along you will have to get your sump drilled bottom line is it's preference and submersible you dont drill and external you have to plumb it. mike

I haev a mag 12 and 9.5 both running in sump, my reactor has a mag7 running external. I personally would put them in sump, But if I could do it all over again I would run external pumps with greater abilities
 . The Mag 12 has been very reliable, 5 years without ever touching it. If you do run a mag external you will definatley need a vibration pad of some sort.
