Can anyone help me figure out why my hammer coral looks like this? its been like this for 6+ months. I've tried moving it around in different lighting but still stays the same. Polyps are extended every day, and even the little baby polyps on the base extend to my surprise. Tank has been set up for a year and 4 months, and I send monthly triton ICP tests out and haven't gotten anything alarming. All other corals are happy, including my acros, so im curious to find out how I can get this guy to return to its normal appearance. Pictures of before and after are attached. Tank parameters are below,
