Issue: tank overall has been doing good, not perfect, but good. Haven’t lost anything.
However I came back from being out of town a couple weeks ago and most of my soft corals are oozing brown a little bit and no full polyp extension. I really am struggling to figure out the issue in this tank and why my sps seem to be fine but my softies just never seem fully happy. I do 10% water changes weekly. I used to run Purigen media backers but stopped because I felt I was starving the corals. Only thing I’m still trying to figure out is what intensity is best with these AI primes. Everyone has a different opinion or setting on them. So I have no idea whether it’s too much light, not enough, etc. I took this setting from a reefer with a very successful tank. I am running this setting at only 50% in acclimation mode.

Any ideas why my softies are pissed off and won’t open?
