Noisy Tunze nanostream 6045

[CyberGuy]

I just got the nanostream 6045 from the FedEx guy today and when I put it in my tank and run it I can hear the noise from about 10 feet away. Is this normal? Do I need 1 or 2 days for the noisy to disappear?

It is producing good flow in my 90 gallon but the noisy it bothering me.

If they are noisy when brand new this usually takes car of itself, the shaft is a bit crooked and just the centrifugal force of the prop rotating should fix it within 3 days. I had the same experience with the Beta one I got in September and it was much quieter in just a day but almost all the noise was gone after 3. If it is too much for you though, I can exchange the motor.
