I also find it's cheaper to buff up the Calcium on my waterchange water than it is to buy more expensive salt.

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.
