Brown film algae in fuge

I have this brown film algae in my fuge. I think it's either cyano or diatoms (not sure which???). It's only in the chamber with my chaeto ball that's rolling. Most likely because of the daylight bulb running during night hours. Is there something that will "eat" or remove this stuff like some kind of snail or hermit? I don't have any sand any there. Just my heaters and my tumbling chaeto ball.
I was going to put a DSB in there but decided not too so the ball can freely roll. The flow is controlled from the return valve that T's off to the fuge which is controlled by a gate valve. I have enough flow to make it roll.
