Salt
As some who has followed the development of salt mixes over the years we allmust understand something.
Salt used for aquarium is generally just the base scientific grade sodium chloride and a additional trace mineral mix with everything we need for aquariums.
One of the largest reclaimer of trace minerals from salt occurs in the dead sea region in Israel where they extract everything from cobalt to gold from the dried brine.
Lots of aquarium salt manufactures buy their trace element mixes form this large operation in Israel hence dd saying that salt comes from an evaporation based processes.
Whether or not who is combining the salt mix, lots of companies use the trace element mix sourced from the dead sea operations. There is lots of information about over on the zeo forums.
Sorry for the long winded answer but a friend of mine is an engineer at this project and you would be surprised how many salt "manufactures" use their products.
