Sourcing high purity NaCl

[Sangheili]

Randy,

Any idea where I can find NaCl of similar purity to those used in synthetic salt mixes? Looking to have a little on hand to adjust SG without affecting other elements in the water.

Thanks

Sorry, I don't know what they use.

The highest grades likely to be financially acceptable would probably be ACS reagent, and pharmaceutical grades (USP and/or BP).

Higher grades will be very expensive.
