Are you testing and keeping you alk stable?Also calcium and magnesium must be keeped at proper levels

Calcium is at 450. Not sure on alk and mag. All other corals are fine. I cut off the bleached limbs just in Case it's an infection.

From your description I think your loosing tissue from the base up.Not bleaching.Most likely alk related,you need a good test kit and keep it steady at 9dkh. Steady is the key,do not let it fluctuate. mag needs to be around 1350ppm

Just tested alk yesterday at the Lfs. It was a bit high. The bleaching started after a pwc so I'm thinking it was an alk swing because of the water change.

Yes looks like alk burn on the tips.Maybe smaller water changes 3-4 gallons at a time. Tank looks like it is still young.Try keeping parameters stable and you should be good. Any fish in there?
