I need help with a really noisy fluval U4

[Pleco1415]

A couple months ago i bought a Fluval U4 for my turtle tank. Ever since it's always been noisy and the best way to describe it is it sounds like there's a rock in the impeller shaft. I took the filter out just a couple minutes ago to do some regular cleaning and I decided to feel the impeller for any chips. I found a tiny piece of what looked to be a sharp piece of plastic hanging off the impeller so I pulled it off. After I put the filter back in and plugged it in I realized it was noisier than it was before. The noise really bothers me because the tank is in the bedroom. Can someone tell me what is wrong with the impeller and how to fix it?

Here is a photo of the impeller.the slime you see on it is Vaseline but the chip is on the left hand side closest to the green.

Sounds like it's knocking due to improper weight distribution.. you can probably order a new one on amazon...

I'm trying to avoid buying a new one seeing as I recently made a trip to the aquarium store. Is there any way I could possibly sand it down?

Cool thanks. I tried fixing the impeller but it did not do anything. I'll have to replace the impeller.

You might try sending an email to Fluval and see if they'll send one out. They've been decent about it with the C-series models
