Is this just green hair algae?

[cyanicko]

Can someone help me identify if this is just green hair algae? Should it’s mainly affecting my corals on my frag rock. Is there anything specific I can do to remove? I have a decent clean up crew but their shells are now covered in algae too. What can I add to help? Thanks!

Looks like hair. Tooth brush and manual removal

^ this and what type of cuc do you have! My tuxedo urchin was the best at plowing through gha. Throw one or two in along with turbo snails, trochus snails, ninja star snails and emerald crabs.
