I’m considering replacing my old mp10’s with 40’s. My vortech are really noisy and my question is are the QD’s really quiet or should I expect the whirling noises? I need it virtually in audible because the tank is in a room that requires it to be inaudible. I’m tired of the noise but love the pump so I’m torn.
