Khuligirl93 is spot on. I have the following three filters on my 38 gallon tank stocked with 44 fish:
AquaClear 50: Placed In service Dec 2013
Fluval C3: Placed in service Aug 2013
Fluval C3: Placed in serice Jan 2014:
And guess what ...... despite my water being crystal clear and polished ...... the filters get filthy and "gunked up." I turn filters off during feeding ....... and within about 60 days ... filter motors won't "self start" due to build up. I use an ice pick to get them going short term ...... then I just surrender and take the motors off and clean impeller, tubing, etc with a Q-Tip & a bottle brush. The tubing and impellers seem to accumulate more "gunk" than the filters themselves. The gunk is kind of subtle in my aquaclear which you can see in this video (taken 10 days ago) .......

but now it's totally filthy and I'm going to clean it today along with a 20% weekly water change.
Oh and BTW: I hadn't thought of a toothbrush ........ thanks for the idea.
As for the mess on the biomax ...... despite the claims that it lasts forever .... you cannot ever make it "like new" and it should be gradually replaced. The instructions say at 6 months or so .......... which is about right. I'd gradually replace the factory bio-media with Fluval ceramic biomax
Even Mr. Cheapskate himself king of aquarium youtube DIY Joey Mullen says you cannot clean biomedia ...... you must replace it:
I currently run Seachem Matrix along with "factory" media in all my filters.
