skjl47, a QuietOne is a water pump, usually used as a return pump.
OP, it has been my experience, I wrap the return tubing with foam pipe insulation where it touches anywhere. Also, a cushion underneath, like pot scrubbies or a piece of foam,(submersible) works great. Also, when the pump gets dirty, at least mine does, cleaning the impeller and impeller well smoothes out vibration.
