Having some zoas starting to act up recently... Some colonies are growing great, others have started cupping upwards on the skirt and mouth is raise with weird coloration. All other corals SPS and LPS are doing great. Water parameters: SG: 1.025 KH:8.7, Calcium 425, mg, 1250, Nitrate 12-16, Phos: .15. Started dosing aminos 2 weeks ago (brightwell) and feed reefroids 3-4 times ago. Also started 4 drops of lugols solution (110 gallons). Not sure if its a light issue or something else.
