If you are getting the numbers you posted above from IO you must have a special batch.
While I do think IO is one of thebetter salts it is horably low in Mg like any other salt as Mg is an expensive additive. If you start a tank with it after a week check the MG and adjust it up to about 1350 to 1400ppm. This will also cause your Ca to raise if it is being supressed by low Mg.
I wouldn't worry about raising a 390 Ca level as that is about as perfect as you can get.
