Oddly, woke up to work light on. Appears left door sensor has gone out of alignment again. Overrode and turned off left light trigger via Apex for now. MP10 also seemed to be out of alignment -- occassional roar. Fiddled with it, and all fine again. First time that has occurred, so perhaps was algae build-up -- cleaned that off with a brush just in case.

Brushed rocks, changed filter material, cleaned skimmer and probes. All set for water change later this week.
