The other day I added a new skimmer to my systems after the Easter weekend which I wasn't around to monitor the tank I came home to find my candy cane corals looking well .. skeletal they were striving well and there has been no changes to the tank aside from maitance and the addition of the skimmer all other corals are doing well I feel like they are dieing but I'm not sure why water chemistry checks out and is stable aside from the drop in phosphate and nitrate since the skimmer all is normal these are the current look of the coralthis is how they looked be for the change
