Is this bryopsis?

Please let me know whether this is bryopsis. Also, are the air bubbles definitively bubble algae?

Your system has hair algae. Did not see anything that looked like bubble algae.

Yes typical hair algae, increase cuc and manually remove. Bryopsis has the unmistakable look of a fern leaf.
