I run a used Emperor 400 on my tank. It used to make a slight clicking noise since day one. Ive replaced the impellar, flow box and the intake tube. I now have a very light buzzing sound. Is this its normal operating sound or is it supposed to be completely silent? Thanks in advance for any info.

Mine is not real quiet. You can hear like a huimming sound.

I also had one one my 55 and and after multiple times cleaning it , it still made a humming sound. How big is your tank? Might wont to switch to a small canister if it has been set up long enough.

So I guess the light humming sound is normal. It really doesnt bother me now compared to the clacking sound mine made before. I also run an aquaclear 300 that hums as well. I can live with it.Thanks for the replies.
