Instant ocean salt parameter

Thanks everyone for getting into the topic. Like many mention here Mg need to be in check before adding cal or alk as I also notice I add lots of A and B dose and calcium liquid as well but still couldn't get Cal to increase pass 370 from 340ppm. Alk in other hand I see it increase so let me get Mg in range and dose cal after see if I can bring it up to 420ppm.
