Yeah, started out with dead rock, tank was cycled for a month and a half before I put the corals in (scroll coral, montipora cap (orange), and a purple superman). The coral died 4 days ago, then I noticed today the bubbles in the tissue on my monti. I just took out the coral and scraped and cut that part out, outside of tank. The rest of the monti is healthy. What is that bubble thing? I never seen it before. My purple super got a small spot of rtn,3 days ago, I cut that out too....
