Hey, I was starring at the media in my sump today and I saw little needle tip size dots all over the glass, and there was some on the bioballs, are those what people call "beneficial bacteria" or should I be worried? None of my fish seem like their in harm or lethargic I know BB are suppose to be micro size but I'm wondering what these guys are
The real questions are, CAN YOU SEE BB with the naked eye?
