I have red montipora cap and seasons greetings coral. Over the past week I just randomly noticed they look ashy. They have been in my tank since November in the same spot. Not sure what's going on. Parameters salinity 1.025 N-8 P.12 as I am FIGHTING dinos I am keeping them slightly elevated but have been since they have been in tank. Calcium 450 all 9.2. Temp 80. I did have a small alk swing 2 weeks ago where alk drop a little but none of the other corals were affected these are my only sps though. You can see the back of the seasons greetings how green it usually is. I have been busy the past two week aswell and didnt really notice small changes.
