Dutifully, I did a 10% water change every day, but it turned out I didn't have to do it for a week, as the pH is already up to tap water level. And indeed, Lord Yeti the killifish has chilled, and the tetras are no longer scared shitless. (They were swimming tilted to side, every one of them. It freaked me out.) No more eyes have been lost.
I continue to love the female. She nibbles my finger when I stick it in. :-)
