Let's back up:
The tank was purchased from someone else who had it up and running 8 yrs. I moved it and kept most of the water, ditched the sand in the DT and refugium and added freshly rinsed carib sea aragonite reef special.
The tank had soft corals, brittle stars, a coral banded and 4 fish. The fish all died within 2 hours of acclimation. The corals are doing great and spreading in some cases. The shrimp molted.
So, it all doesn't make sense. But i'll be getting the new test kit soon and see what it says.
