I'm sorry but I'm going to be a bit of a downer here....
I dont see how your tank is cycled. You mentioned you used established water... unfortunately that doesnt help much. The bacteria you want would be on the rocks, and you said you used dry. That old fungia plate helps, but not much. You're testing for nitrate, but how about ammonia?
That last pic looks pretty cloudy, I would test for ammonia asap and slow down on adding anything for at least another week or 2. From what I see the tank was started on 1/15? It's only a few weeks old, way too soon for coral imo. Goodluck though, and I hope I'm wrong and it all goes smoothly for you.
