Alge question

[ThePrincipal]

I am new to the saltwater hobby and have a 29 gallon Biocube. It has cycled and is starting to grow great coraline (purple) algae. However, I am also getting another type of algae that looks like grass. It is popping up in small clumps on the rocks. Any idea what it could be or how to get rid of it?

Thanks

Sounds like Green Hair Algae.
