I’m going to guess Chrysophytes. Do you have a microscope? Can you borrow one?

Looks like a part of the ugly stage. Set up a sock or something similar in your sump and siphon this stuff off.

I also think chrysophytes; we need more info, though. How long has the tank been up? What are your water parameters? (Nitrate, Phosphate) Have you been doing water changes? How big is your tank? What does your bioload look like? How long has this been happening? Have you changed/added anything recently? Have you had any other algae before this?
