Vibrant +1.
Within a few doses the bubbles turn white and die. I'm unsure if it completely eliminates it from the system as fluconazole does with bryopsis, but it certainly works and gives you a fighting chance. The intention is that Vibrant continues to be used as a lower maintenance dose basically forever. But make sure you don't let it take your nitrates down to absolute zero or your corals will suffer.
Also, a small army of emerald crabs does put a dent in it.
Urchins eat it when it's physically accessible to them.
Vibrant All day! Hit it hard! Foxface all day ! Good luck.
When I was younger I took down my tank bc of this stuff.
