i use oceanpure salt. it has crazy high magnesium. when i mix to 1.025, it's mg is around 1500 ppm. It's calcium and carbonate hardness are imballanced when it's freshly mixed though. high kH, but low carbonate. I think that's why dosing kalk is a pain with it because i'm starting with imballanced water.
