My java moss is looking a bit funky lately. Brown fuzziness on parts of it. What type of algae am I dealing with? It's in a 5.5 gallon tank with a 10w cfl. Too much lighting (approx. 7hrs a day)? It's in a bright room as well. FYI: This tank has a betta, a nerite, java ferns, java moss, anubias and some other stem plant...I forget its name. It is cycled with nitrates hovering between 0-5.
