Noisy Koralia? Easy Fix!

My Koralia #4's were getting lots of growth on them so I thought I would clean one of them. When I put them back together I was getting a very annoying hum. I took them apart again a few times but nothing helped.

I read on a post here that there should be a washer on the bottom of the shaft where it sits in the motor. I must have lost mine when cleaning. I don't have any washers so now what?

I took a piece of RO/DI hose, the hard plastic type ( we all have some of that laying around ) and cut it about 1/4" long, slipped it on the magnet end of the shaft and no more noise. I can't even hear them runing now. Easy fix and it took me less than 3 minutes to do.
