This is not something I've ever seen before. They are extremely ugly. Mar the appearance of SPS. This is on a "Beach Bum" encrusting montipora. I would take aphasia or even montipora eating nudibranchs over this crap. I've beat those with hard work. Not sure how to eliminate these without killing coral.
I read a thread sometime ago or maybe it was a YouTube video about an Aussie coral grower who raises their potassium to extremely high levels to eradicate AEFW's. KCl is an effective dip to kill nearly anything on a coral frag. I am willing to do this to my tank to get rid of these. I realize it will kill nearly anything else in the tank as well. I would remove snails, inverts, and fish. Perform a 100% water change and reintroduce animals back in the tank.
I don't know, what are your thoughts on how to handle these?
