Hello all. As the title says whatever this stuff is has killed 2 expensive corals. Ive had cyano and this seems totally different. It covers the coral like a blanket and once the coral is bleached it just disappears. I tried washing it off and it just comes back and it's really aggressive. It doesn't spread to other corals. It just vanishes once the particular coral is dead. Any idea on what it is and what causes it? Thanks in advance.
Edit: i added a couple pictures as requested
