After doing a tank clean yesterday, rock brushing and sand bed vacuum, i woke this morning to find my elegance coralnot opened as much and has this white mucous like sloughing around the outer perimiter. I noticed some sand on it, so I’m sure it’s irritated, but I was not sure if this sloughing was a normal reaction, indication of a growth spurt, or something more nefarious like the start of ECS.
