6 months later I've had no problems.
Maybe it was the salt itself as I was using the same source as now, but I won't take the chance.
Of course the other flip to the coin is that I use softened water, which reduces calcium and mangesium, from the water before my RO/DI filters. Of course I hadn't thought about looking into that until recently either.
Not to offend any Marine biologists out there but IMO when people hear of things spoken from a biologist, it is stated like it came from the proverbial burning bush. I always use discretion even when taking advise no matter who its from. I look at it this way, weather or not they finished first in their class or last in their class at the end of their schooling we all call them Dr. I hold the same reserve for other professions whos reputation doesnt preceed them. My guess is you issue with lack of trace elements was from the salt mix you used and as a general rule its just common sense to test for anything you are thinking about dosing. Just my 2 cents...
