Algae appeard in the last two weeks

[buddy.]

Hey guys,
My dad is looking after my tank at the moment while I am away and I visited to see a bunch of new algae that wasn't there two weeks ago. Could I get an ID on them please.
I have the feeling the tank may have been overfed. I plan on doing some water tests this weekend.
Thanks!

First pic looks like Bryopsis to me.

Looks like bryopsis to me too. (Great close up pic by the way.)

Thanks, that was just a quick picture straight off the phone!
I guess I have another algae battle on my hands

Bryopsis responds well to fluconazole treatment.
