    Well, last night I re-calibrated my refractometer using Aquafina or Deja Blu, I forget.

    But then today when I went to a LFS, and used their R/O water it needed recalibration again.
    So who to trust...

    I tested my tap water, and it was consistent with the store's R/O.

    Either way, if the store and my tap water are correct, I didn't really need to recalibrate it.
    The tank water is around 1.027, so I just need to take it down a tad.

    I really didn't think it had been at 1.030-1.031 because the fish and all other corals were acting completely normal.

    I'll still get it down to 1.026 or so, but I don't think that's the problem now. I think the Duncans are just real mad.
