Filter media turned brown, why?

ok that's definately not the biofilm from nitrifying bacteria.

looks more like accumulation of mulm+diatoms+excessive biofilm.

i use momotaro too and the colouration from nitrifying bacteria should just be a light yellowish tinge compared to the brand new white.

one thing u can try is to place the momotaro straight up instead of lying down... that'll give better water flow through it rather than around it.
