Tried testing CA and the solution just won’t turn blue (has worked before). Either my test kit is faulty or my calc is way off the charts.What are your Ca and Mg levels?
Watch out for precipitation.
Also with low nutrients and high Alk, you run the risk of burning your corals.

Had the same issue with Mg previously so I bought a salinity kit for it. Will test later.
I think I should be good against precipitation.... I let the stirred kalk settle for 2hrs before I use it in the ATO. Also 1tsp per gallon is middle of the spectrum. Anything above 2tsp per gallon will precipitate.
