Nothing special just limited the lighting to 4 hours a day for a little over a week, ramped up the GFO and carbon to get rid of organics and PO4. Scrubbed all the rock and did a few water changes. All the corals in the tank got pretty stressed during that time frame with the lights out, I noticed some die off on the others as well.
Just wanted to make sure it wasn't a pest or anything else. So it could just be die off from the lighting change I suppose. Hopefully it will may a comeback with the lights back to normal schedule.
