    Some of the coral is looking distinctly unhappy after my vacation last week.
    Jack-o-Lantern Lepto looks like it is toast.
    It was looking a bit pale before, with a few thin spots, now it is really looking white.
    Tips of some SPS sticks are not looking great either.

    The usual Alk/Ca/Salinity/PH/etc all seem ok.

    My big suspect - starvation.
    I started up my old Algae scrubber when I rebooted the tank, to get rid of all the crud.
    My Nitrates have been dead zero now, and little algae grows except in scrubber.
    When I was gone, it was only auto-feeding pellets to the fish, so that may have taken it over the edge.

    I have had similar looking problems in the past when Nitrates stay really low like that.

    Time to disconnect the scrubber.
    Probably do some big water changes as well, just in case.
