hey guys i noticed this morning that one of my cannister filters is making a ratteling sound,is it time for a new impeller,its not that loud,but normally this filter is whisper quiet,and will a rattley impeller effect the performace of my filter,i gave it a good clean put it all back together correctly,and its still making the sound,what do u guys rekon,a new impeller or what?

Hi,
The noise could be attributed to allot of things. You will
need to tear the filter down so that you can see the
impeller and its compartment. The impellers make noise
when there is a snail, or piece of gravel or charcoal in
it. A piece of floss will also cause it. Air trapped in
the impeller chamber will cause it, and the last thing
is wear. A worn bushing will also cause it.

Tear it apart, clean it, and be sure there is nothing
else in the chamber. The last thing is to replace the
impeller and bushings.

It sounds like the impeller to me. They do suffer some wear after a while which can cause some wobbling and thus the noise. Also if one of the impellers gets off balance it can cause vibrations. I would just replace it and you should be fine.
