I put a piece of rubber under my 24. Keeps it from vibrating against the sump bottom.

maybe it is sitting a little off level and the vibrating is because of that, i found that if my tubing holds my mag 12 at the wrong angle against my sump it will vibrate loudly. i am using the rubber pad also.

I have one that makes god awful noise when it gets airbubbles in it. Or worse, if it is turned off, and then turned back on, it makes the noise either way. While on, I have to take it out of the water, and then put it back in for it to keep quiet. The heck? Any thoughts?

your right , left it up a drop no noise, back in noise again.
but new it was all right. i put an elbow in the inlet so it sucks as low as possible in the sump. tonite I am going to place my sump on a 3/4 drop ceiling tile , that should absorb the sound I hope.
merry christmas to all
