Fine but the point of originally using P.Chloride is to allow it to push Bromine and Fluoride for those salt sensitive.
The P.Chloride (not as effective as salt) helps to work along with the Salt. One can then change the ratio over time from 1:1 to 2:1 in favor of salt...
This way one can use Lugol's while being bromine toxic and salt sensitive, still pushing the crap out of the kidneys...
