Green cyano. 0 no3 and po4 prob the cause. Your Alk is also low.

It is leafy. What's the best way to remove it?

A yellow tang would likely gobble it down. Biological control of green algae (not cyanobacteria) is usually much easier to manage than chemical control.

I agree that raising phosphate and nitrate is desirable to avoid dinos.
