Anyone Seen this Algae Before?

Anyone ever had this type of algae? In the 10 years I been reefing and the MANY tanks I have setup, none of them have had this brown, furry kinda algae. It's not bad cause it wipes right off, easily come off the glass and rocks. Doesnt grow on corals or sand. A water change and it dies off but after 2 weeks it's back. It's not dinos or hair algae. Not a problem algae but I would rather it not be in the tank.

I cant even find anything that closely resembles it , I was thinking calothrix but looking again it don't come close

Looks like Filament algae gone wild.
