ALGAE ID HELP!

[birddawg]

Hey everyone does anyone have an idea what this algae is? Is very easy to pull off the rocks, but it also forms in balls on the sand. Don’t have any idea what it is and it just showed up about a month ago. If someone knows what it is, what is my best solution to fix it? It looks reddish underneath blue light, but as you can see in the pictures below it is green. Someone please help!!!

You think it’s GHA? This algae is easy to pull off the rocks, I thought GHA was hard to pull off.
