It can be submersed no problem. Usually quieter. WHat style drain/overflow are you using? With a Durso, you still get air, which will bubble to the top of the sump if you have the pipe submersed to far. WHat I did was have the drain go to a 90, then into a T on its side. the upper part of the T vents the air up, and water goes down. It can lessen the noise and splashing.
But on the 150g, I run a Herbie style with the gate valve, DEAD silent drain
