My alk and calcium consumption has basically dropped to zero, so I know something is not right. One of my SPS is RTN from the base up, and fragged the tip to try to save it. The base is bone white already. I may send in another ICP just to see what the heck is happening. Very strange. I doubled checked all the major things I can test for, and all looks good. pH is 8.3, alk 9, cal 420, mag 1390, nitrates 16, phosphates 0.15.
I'm out of salt, so I need to get another bucket. /sigh
