Hey I aclockworkorange I went back to the store and replaced the motor, now its as quiet as a mouse, I love fluval things even my heater is the smart fluval heater.
the filter is as quiet as a mouse now and I love the service from fluval and my lfs, I just gave them a call and they were literally waiting for me with a new fx5 but i Just replaced the motor unit since I had everything set up.
Now the filter is even more quiet than my marineland c-530 which does 530 GPH and is same size.

I also have an underwater filter which is 150 gph so totals out about 1500 gph up to 1000 gallon tank filter.. um very good
I hope my water is clear soon
but my tank is having a mini cycle.. .25 ammonia now =/ i hope it goes well
