Greetings Everyone,

I am very excited about starting a new tank, I hope to share as much as possible along the way ... this build will be all Tunze with the new IM EXT series that runs a Herbie style drain.

I have a Tunze 9410 DC in place as my skimmer and my return is a Tunze 1073.04 ... Tunze ATO coming soon ..... tank has even yet to cycle.

The 1073.04 may prove to be too much pump for this setup and if so, I may go with a .03 but at this point in time, my main issue with the .04 is Noise and Vibration.

I have a silicone matt in place and even went so far as silicone tubing. Even with the silicone tube, you can still fee TOO much vibration IMO all the way up the standpipe.

Average Decibels with the pump running alone is about ~ 53 decibels.

I noticed some curious dimples on my impeller shaft that I'd never seen before on other Tunze pumps, four in total uniformly space, you can feel them as they are slightly raised.

I wonder if this would be causing the vibration that is causing so much noise?
The vibration is constant, even if you suspend the pump. I truly am suspecting this impeller.
