    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.

    Things were doing well again - and now an Alk problem.

    We had a small power failure, usually no big deal.
    But for some reason my Litermeter doser decided to put itself in a "ALL PUMPS OFF" mode.
    And I did not notice for a while.
    Alk was about 5 when I tested it. Ouch!
    Corals are very unhappy.

    Yikes, 5?!! How long was it off? How aggressively are you dosing to bring it back up?

    Probably off for a week.
    I also dose Kalk on a separate system, so it did not crash too fast.
    Not bringing it up that fast. Damage is done to a few SPS, others are fine, crazy swings might make it worse.

    Saw this tank yesterday. It’s awesome! Going to be really nice when it all fills back in.

    This stick is probably toast due to Alk mishap. Still some pink showing, but algae is growing on dead parts.
    Encrusting corals and softies are all fine though.

    Maybe do a bit of trimming? It looks like it’s got some life left.

    A fun graph of how Alk levels show up in PH.
    The first two lows were from when Alk was bad.
    Then I gradually added more. Now it is still a bit low, but fairly stable.
