I just added an external Gen X 55 pump and Im getting a vibration from the sump. It seems to be coming from the side that the pump is connected to.
I have about 3" of flex tubing connecting the two and there is annoying vibration sound.
I have put styophone under the sump.

Any suggestions?

Silicone tubing on both the intake and output will help to isolate vibrations. Spaflex and rigid PVC make the sump hum. Also try a dense carpet padding instead of the styrofoam.

silicone tubing...is this the regular vynal tubing? would this work to connect to the sump? Where can I get 1" ones?
also dense carpet padding,,,thats the stuff they use under the carpet right? Wont that get all moldy after years?

Actually, I meant vynal tubing, but high quality vinyl tubing has a high percentage of silicone in it for softness/flexibility. A good LFS should have high quality tubing in 1". As far as the foam, that area shoul be dry, but a dense foam will not absorb lots of water....and it is cheap to replace if needed. Just buy a length and save some
