I consider filters to be nothing more than nutrient storage units, and unless you clean them often, adding more stuff to the filter does nothing but recirculate this invisible nutrient load, because in the filter is really still in the tank.
I consider what you can't see, to be often times more dangerous to the health of the system, than the non-aesthetically pleasing stuff you can see.
I prefer vacuuming up the debris, thereby removing it, and old water (and fish urine), and replacing with new.
Pushing more stuff in the filter, is to me, like sweeping stuff under a rug.
