There have been many discussion about the use of polyester fiber (a.k.a. Fiber floss, poly floss, Fiberfill, etc.) as a media for filtration and it's efficacy. Those like myself praise the value of it. Since some people cannot envision the use of it, I have included pictures of how I use it.
This is on an Emperor 400 and I do the same thing on all power filters regardless of manufacturer.
First thing I do is to take a worn out cartridge and strip the media and dump the carbon.

I then insert it back into the filter and moderately pack floss between it and the back of the filter. (Bio-wheel has been removed for better viewing).


This is how well it works at trapping dirt and waste. Keeping in mind that this is a wad of fiber, it actually has more particle trapping surface area than a manufacturer cartridge. I change the floss about 1-2x a month or as needed. Some of my smaller tanks get changed less often due to the light stocking.
