Algae ID - Bryopsis?

[burner7]

My tank is about 2 months old and I added TBS live rock about 3 weeks ago. I am trying to identify this algae that has been popping up in my sand. Is it bryopsis? It pulls up easily with short roots and no rhizomes. My astrea and nassarius snails don't seem to eat it.

Looks pretty much like it.

Usually I say that all algae growth is totally normal during the first months when the ugly phase hits, but I have not gathered any experience with a bryopsis ugly phase... Usually the green hair algae (e.g. Derbesia) dies down on its own, but I don't know if that applies to Bryopsis.

Maybe someone else knows if this is a problem.
