I don’t measure it’s level of Magnesium, Calcium, Potassium and such, so I don’t have those data.
But I’ve been using it for years for LPS and softies and all are growing fast and fine. I don’t do SPS, thus can’t comment on that.
I like that the salt dissolves very fast into a clear mix and I never had issue of “white” precipitate, even if I dump all the salt in very fast.
