What is this growing on my zoas

[ATC]

About every 3 days I get this clump of greenish brown growth up close looks similar to a fern leaf. It’s very tough to manually remove but it keeps coming back and im starting to get frustrated so question of the day what is it and how to get rid of it. Tank is a 22.5. Any help would be awesome I’m at my wits end.

Pics very fuzzy but looks like bryopsis algae and is one of the harder to combat
You must remove the root or it keeps coming back
Best method is to pull roots with either a dental pick or small crochet needle- best done outside of the tank

Your description sounds like bryopsis. Flucanozole is your best option.
