Got this as a free frag a couple months ago. My guess was that this was chalice? Not totally sure. It lost a bit of flesh the first week or two but then bounced back. Since then it has been fine until the last week or so when it began losing color and has become a bit pail. What exactly is this. Running noops at 40% 12 inches off the water. I will try to get parameters for you this evening when my wife gets home. I am colorblind and testing water is tricky other than phosphate(Hanna).
