Am I adding coral too soon? Had a 3 year old mixed reef that crashed when I bought home and moved in November. Never took rock out of water. Ran carbon heavy for a month. Setup new tank 3 months ago and used 1/2 same rock and 1/2 new dead rock. Used all new live sand. Levels are all good! Testing daily. Already have doser back online and chaeto in sump. My nitrates have been 5 for 2 weeks. Alk 9.2, calcium 450, mag 1350. No phosphates.
