Quick update: I finally broke down and took the kalk stirrer online. The Alk solution part of the two-part was offline for a coupl of days before that. The alkalinity took a couple of days to fall to today's range of 7.6-8.2. Which leads me to think my corals have shut down. What puzzles me is that I am now only adding Ca solution (part one of the two-part) at the same rate as before the STN started, and I can barely keep the Ca above 400.
I noticed STN startingin in a couple of other acros, including my green slimer. This is truly tragic....
