no ATO, i removed the blue sponge filter that was in front of my pump and rinsed it out, though it wasn't particularly clogged, and changed the filter floss, which was really dirty, i admit. that may have been disrupting the flow from chamber 2 to chamber 3. i did a top-off about 2 days before, my level hadn't noticeably dropped. i assume it was just the disrupted flow.

My red sea max has done this before, however non of my corals got angry. Are you certain nothing else happened? Has your temp gone up/down during this time?
I do know when I frag my sps they will slime up pretty bad but within an hour or so they are back to normal.
You should be fine.
my heater had no signs of disruption, i'm pretty sure it held solid. my params are all normal.
