No coral growth and some closed up candy can coral and a closed Duncan. Tank does not seem to be thriving. Numbers are decent. Nitrates 3 ppm and phosphate is from 0.02 to 0.08. Alk calcium and mag never drops any. I haven’t done a water change all week. Found out recently that my nitrates bottomed out at 0 a brought it up this week some. Corals never seem to grow any my salt stays at 35 ppm Any help?
