Algae cyano or something else?

[QuiGonJay]

Been struggling with this for awhile, is the brown patches on the glass algae? It comes back in a day or two, easily utility almost like a film. Trying to control bubble algae so recently started gfo. I just haven't seen this kind in the tank before and the clean up crew ignores it. Didn't think cyano grew on glass but maybe?

It's called film algae and you need to clean your glass every two or three days and clean the algae off of the glass.

Sorry for asking a pretty stupid question, but honestly I havent seen it in my tank before, usually only have to clean the glass every week. But good to know it's just normal.
