Brown fur balls on my air stones

[Señor Discus]

HEllo, I just noticed today that I have got some growth on my air stones. They look like little fuzzy brown balls. I was wondering if it was some sort of algae, there is none in the tank so far that I can see. The light is regulated as it is a Finnex 24/7 and the tank is young, 1.5 months. Has this growth ever occured with you?
Thanks for the help fellers!

nahh just sounds like normal bb (beneficial bacteria). Its good for your tank, as its the same bb that grows in the filter in the biological part, but if you want to clean it feel free to wash it off with clean water, or change air stones.
