Algae ID

[reefs4lifee]

Can someone please ID this algae for me. It started growing on my eductors out of no where ever since I've been in a fallow period (about a month now). It looks kind of nice and when viewed from other angles it sometimes reflects blue/green. Thanks in advance, Fortunato270575

Bryopsis Pennata I believe. Common name sea fern. Many consider it a pest algae, but I don't have issues with it myself. I have a large algae CUC, and I have other macro algae that outcompete it.
