nasty brown stuff!

ok so today i cleaned out my filter nad stuff, i have little round spounge (sp?) things around my mazi jets and my skimmer, and its like a little filter i cleaned those out also, well they were full of brown gunk stuff that smells HORRIBLE the brown stuff is even on my heaters, its honestly one of the worst smelling stuff that i have ever smelt ahah, even thouse i completely cleaned out the spounge things like only clear water came out instead of brown, it still smells REALLY REALLY REALLY bad, what can i do, is there any way to completely setolize it and get that smell out? b.t.w. i have a reef so its gotta be reef safe

 

no one?

 

Got any pictures of it? Is it algae do you think? What type of clean-up crew do you have?

 

well i got a cleaner shrimp, 10 or 12 misc. snails, and hermits, its not on any of the rock, i only have coraline on that, its just in the sponge things and my filters and the thermoters for some reason

 

Not sure. Sorry. Maybe someone can figure it out.

 

im guessing diatoms, they smell like crap and looks brown
