This is the one that's more than likely NOT Bryopsis
Just hope it's not as bad. Got to do more search on the type John @reef cleaners thinks it might be.
I will try for a macro shot picture if it comes back & I know it will....
This one looks like a variety of cladophora. Compare pics below and see what John at reefcleaners thinks. Unfortunately it is another nuisance algae that is difficult to remove.
