Today when I checked on the tank, it was a little milky looking. I checked the ORP, and it was around 231 (instead of 300+). One of my circulation pumps had stalled. I got it started up again, and the ORP rose to 278 and the water clarified.
Of course I couldn't leave well enough alone, and tinkered with this and that so the ORP dropped again but I think it'll rise up more.
Nitrates appear to be about the same as of last night.
