My tetratec 1200 external filter since being set up has brown gunk all in the filter pipes leading to the spray bar, which when you squeeze the pipes rushes down and into the spray bar. 
The spray bar is also covered in brown gunk, the tank is fairly young and only been running for two months.
Is this just due to a build up of poop or poor filtration? and if cleaned is it likely to come back?
