Help Identify Algae!

[Goldie-Maree]

this has been popping up in patches everywhere. Is this a bad algae that needs taken out?

Pretty sure it's Bryopsis. Very bad/invasive algae.

Hopefully I'm wrong and someone corrects me with good news!

Follow below link, my algae looked the same. Pulled rocks out and spayed peroxide on them. Next day, gone. You have Bryopsis and hair algae, will kill it.
