Never have experienced this and it’s pretty much gone but just wondering what could have caused it. My parameters have not changed much. Did a 5 gallon water change just to remove some detritus. It may have been slowly coming on but by the time I noticed the interior of the colony was gone and Two days later it’s only the tips left. I have frags of it on the other side of the tank with no issues but they get less light. Could it have gotten too dense for proper flow? Just trying to avoid it in the future. Managed to clip off a bunch of tips for frags so not devastated but just concerned about it happening to something else. My temp has been slowly creeping up but nothing drastic. My mag also went from 1350 to 1450 but everything else has been stable.
