I try not to add it to my tank, it is a simple matter to replace the salt durin a water change, but the salt is not the same anymore.
We had a similar thread awhile back and when one of our advisors posted to it his post rang true to me and I have held this view since.

It is no different than adding rock salt to your tank. Sure, it contains some trace elements but during the evap/condensing proceedure it has combined into crystals or combined with another element.
Ditch it or put it in a bottle and tell your significant other that it's g e n u i n e sea salt.
