I have a couple chalices that look pretty bad all of a sudden, the Purple Urkle and the Watermelon in the foreground. Params look normal, all other chalices and SPS look fine. There are a couple with white patches on them in the last 2 days or so. Under 6x T5 w/ Led supplement. The tissue isn't gone, just appears to have been stung/burned or something and is transparent. Nothing is close but other chalices and they have been fine for 8/9 months. Should I dip in something? I have Revive, CoralRX and Bayer on hand.

If the tissue loss continues, you can always redip.
