EVO13.5 pump

[LI2NC]

My daughter and I both have EVO13.5 with Sicce 1.0 return pumps with a few fish and some coral. My pump is noisy, her pump was quiet! I recently put my stock pump back in my tank and it is pretty quiet. I went to do a water change on my daughter's tank and turned the return pump off. After the water change I plugged in the pump did not start! I knew how to take it apart and how to clean it and put it back together so I did just that. I noticed the impeller magnet had cuts in it possibly from barnacles or small build up of something cutting into the magnet but it was running quietly. I cleaned everything and put it back into chamber #3 and plugged it in. NOW THE PUMP WENT FROM QUIET TO NOISY! So I was thinking to 1) replace the impeller and hope that was the issue (I don't think this the issue) 2) buy a Sicce Syncra Nano pump so there would be nothing touching the tank other than the 4 suction cups. The Sicce 1.0 is a VERY tight fit in chamber #3 which was why I thought my pump was vibrating on the tank.

Any one using Sicce Syncra Nano in their EVO13.5?

I used to use that pump when I had that tank running. I don't remember any noise problem, but it could be the impeller. I don't know if you would he happy with the flow rate of the nano, it might be less than the stock pump.
