Hi, I have zoanthids that are supposed to be yellow and have turned green. Like the outer edge on wwc purple monster zoas. for example. I have yellow submarines that are still yellow and Blondies that are still yellow. I use Red Sea pro salt now I just order the blue bucket instead of using 12 dkh salt. My viper spectra lights are at 50% blue 1% white mounted 15 inches above water line. Why do some zoas that are suppose to be yellow turn green? I do weekly water changes so every parameter is Red Sea pro parameters. I just added the zoas to the tank a few weeks ago
