I’ve had this frag for one week now. I noticed the other day this spot started lower but above the base. The frag itself has decent pe and otherwise appears healthy. When the white spot first started it did look like there was a tiny visible hole in the same location. All other frags appear healthy. It’s a frag tank. Over 10 years old. Nitrates did drop to 0 according to Hanna a few days ago. They usually hover around 2-3. Other than that I plan on getting them back up slowly. Long time lps fairly new to sps
Thanks
