Help identify brown fuzzy algae

[tmhickey2023]

Hello Everyone,

Have had my tank up and running for about three months and just found this algae growing on my rock. It appeared a few days ago out of nowhere?
PO4: 0.03 ppm
Alk: 9.0
NH3: 0.05 ppm
NO2 and NO3: 0 ppm
Salinity: 1.025

Thanks for any help or advice!

I don’t see brown fuzzy but do see pale colored fuzzy. I wonder if this a Chrysophyte infestation.
