on my whisper 60 i took out that black square bio thing that goes by your filter and left it in the kitchen sink for a few days and now its FULL of mold and crazy fungus of biblical proportions... all of which look very septic and vile.. to the point that i want to throw it out, but people say the bio square is irreplacable and NEVER throw it out...
so does this mean my entire filter system is useless and i gotta buy a whole new one just because of this one little part?!
