SPS turning green...?
My concern are SPS corals are turning green? What could be the reason for SPS too morph to a green color from a vibrate coloration.
Parameter are listed below (all parameter are solid and stable) Salinity - 1.025sg Temp - 78F Alkalinity - 8-9 dkh Calcium - 430-440ppm Magnesium - 1370-1430ppm Phosphate - 0.18ppm Nitrate - 2-4ppm Lighting are 4 T5 bulbs in the order of front to back. 1) ATI Blue Plus 2) ATI Actinic 3) ATI Purple Plus 4) ATI Blue Plus Tank is a 4 feet by 2 feet by 1 feet frag tank. The tank has been running for 2 years going on 3 in July. SPS have been accumulated to the tank for about 2 months maybe longer. |

Po4 is kinda high but I don’t think that is why? How long have you had them in your tank?

Are you dosing anything else for trace elements? I know excessive iron may cause the corals to turn greenish.

I am currently only dosing Alkalinity, Calcium, and Magnesium from BRS 2 part. As for Phosphate, I realize that the values are high, but in the process of lowering them down to 0.03 to 0.08. SPS have been accumulated to the tank for about 2 months maybe longer.
