It is probably a lot higher than 99%. Pickling salt is food grade
with no anti-caking additives nor iodide added. It is the purest form
of NaCl that is generally available, and should be fine. "Rock salt"
would probably be OK also; it is not all that pure, but the impurities
ought to at least be "natural" (like dirt, traces of KCl and CaCl2,
etc.). "Aquarium salt" looks like repackaged water softener salt to
me.
