Hi all, I am trying to figure out to cause as the what’s wrong with my torch coral. It has been closed up for a couple of days now,(granted this pic is over night with lights off.) I tested my nitrates and phosphates, Nitrates at 18 and phosphates at 0.75.. Both are a high correct? I’m not running a skimmer, and have been relying on weekly water changes for a week now. Should I dose anything, add more cleanup crew, change my filtration setup? Any advice/help is appreciated as I would rather not lose my torch haha
