All filters and tubes over time (at least for me) always get a brown, slimy, buildup. It wipes out easily and I always chalked it up to a thick biofilm type buildup. Algae can build up in biofilm along with detris and you get brown gunk. I notice it's worse in some tanks than others but also seems to just naturally build up over time. I've never worried about it since it cleans up easily and has never caused problems.

I have seen video on Youtube of filter pipes and filters that were a solid brown mass. On plantedtank.net someone told me you never have to clean this off. 
I cannot believe that this does not affect filter flow. It looks bad too. I notice mine is worse in warm weather and has gotten a little worse since I started using dry fertilizer. I clean my filter pipes at least every two weeks. I clean my filters housings about once a month.
