Thanks. All my local Kroger had was brand-name Morton rock salt. Bought all
28 lbs on the shelf for a lovely $10. Also found enough malachite green and
formaldehyde solution for $38. I should have gone to the office and pilfered
a hundred little biopsy bottles of formalin and thrown them in. Sure would
have cost less.
We shall see if I killed or saved my fish.

Kosher salt, at the grocery store.

High grade, reasonable sizes, easy to find.
