Green type of algae

[tjsweldind94]

I have had this tank for 2 months, I had some Cyanobacteria (red slime algae) but got that under control, im trying to figure out what’s up with this green algae I’m fighting is it coralline algae or a bad algae, I just tried reducing the intensity of my reefled 50 I’ve tried to scrub it off the rocks with a tooth brush doesn’t budge but it now looks to be on my sand bed and glass it doesn’t just wipe off the glass picture is with just white light on it doesn’t look bad with blue added

PS corals are doing great closed cause the light is off normally now just wanted to snap a picture

Do I need a bigger clean up crew? I have 2 sapphire hermits and 2 snails, any recommended fish that clean algae that get along with clowns and corals?
