Turned whites all the way up for better visibility. Just now realized myself how bad it got because I never have the whites this high smh. Luckily it is primarily only on this specific rock, but there are patches on the back wall of my tank (I have an AIO so the back isn’t glass.) and other rocks, so it is definitely spreading and at risk of getting way worse. I’m currently on day 7 of Reef Flux and it really hasn’t done anything, but I no longer think this is even bryopsis. Can anyone confirm what type this is so I have a little bit better idea of what kind of treatment I need to do? I might have to try Vibrant.
