In the last year I’ve noticed most of my corals have really slowed down in terms of growth. Though I have a few SPS that grow like weeds. Also my LPS aren’t as vibrant as they used to be. Currently I add kalk to my top off and run a Ca reactor as my only source of supplementation beyond water changes. I’m wondering what can I do try try to bring some of the color back and maybe supplements are an option for that.
Does anyone have suggestion on additives that could help with coral color?
