LPS corals are generally very sensitive to damage; an exposed skeleton is always bad, as algae can settle there and the coral will slowly die while the algae grow. I had a magnificent plerogyra in my time, but it perished due to damage and an exposed skeleton. Although in very good conditions it can regenerate tissues and restore its skeleton, the water must be of very high quality for that.

Yes, it is indeed covered with microalgae, and this damage progresses slowly but surely. Although the coral itself continues to take in food, it inflates quite healthy bubbles and at night, or when it senses food, it releases its tentacles.

I had the same experience, and gradually the algae increased while the coral died. The most unpleasant thing is that it is almost impossible to remove the algae; they get their nutrients from the dying tissues of the coral and continue to expand their growth area.

It is said that increased (within reasonable limits, of course) iodine content sometimes solves the problem... I had such an issue with the newly brought Trachyphyllia and Catalaphyllia. I poured in one and a half doses of iodine and continued to add the usual amount, but more frequently. Trachyphyllia recovered, but Catalaphyllia - alas...
