Wow! That's a new one to me. All kosher salt I have ever seen was ground a
bit coarser because anti-caking stuff *wasn't* being added. Live and learn.

The bad stuff for fish, in *most* table salt, probably is silicates (silica
gel) used for that purpose. They form an insoluble cloud and apparently it
can clog gills. The iodide is at such low level it's never a problem.

Some cheaper table salt contains sodium ferrocyanide for anti-caking. AFAIK,
it's perfectly safe for fish, as friends have been using it for years. To
keep from totally freaking out those "educated" in government schools,
you'll often find it called by the rather antique name "Prussiate of Soda."
