Can anyone I'd this algae?

Having trouble finding out what the brown stringy algae is, fairly new tank 4 months up and running only 2 fish, and a few corals and this stuff grows like crazy on my back side of the sand I would say cynao but isn'tthay red? Anyways its a biocube 29 running purigen, chemipure blue and carbon. Purigen and chemi pure is most likely exhausted, I ran those since I started the tank maybe they are the culprit? I also have a skimmer so idk what it making this algae grown I don't over feed and my one cleaner shrimp catches the left over my clown and wrasse don't eat so idk ive been keeping up with my water changes so maybe turn down my lights intensity?
