I had cycled my tank for several months now and had stocked my tank (15gal) 4 days ago with two firefish and a banggai cardinal. I've only fed them twice (pretty sure did not over feed each time). Nitrate levels read 20ppm (although it was 10ppm when I first stocked). Today i noticed this white fuzz growing on a couple of my live rocks. Looks like a bulb and then has hair like filaments coming off the top. I am not sure if it is algae or not. Should I leave it? Or how do i get rid of it? Please help, thanks!!
