what pum is better for return on 120gl mag12 or Quiet One 5000?

I'm using a quiet one 4000 on a 120g; however I will be running a closed loop system down the road for more flow.

Both good pumps. If your gonna run internal, I think the quiet one runs a little cooler. If your gonna run external, Quiet One would be my choice. Mag does not recommend running their pumps external, though a lot of folks do with no problems. I've had both.

I use a QO 4000 and have had no problems in over a year.
