I've been dealing with this algea for a couple years now with no success. Nothing eats it, not even lettuce slugs. Which makes me doubt its actually bryopsis. Flux rx works to an extent. But it just grow back before you can blink.

Looks like GHA in the second image.
It kinda does but it grows throughout my entire tank and it has been for quite a while now. However nothing wants to touch it. No blenny, rabbit fish, tang, shrimp, snails, mitrax, hermits or urchins.

The two pics look like two different species, both algae, not cyanobacteria I think. If macro algae is infested with cyanobacteria, it might not be so appetizing.
