You basically said I was partially correct while reiterating exactly what I said. People (not you) seem to be caught up in the whole dosing part of KHD and don't understand how to use it. It is a test to show where Alk is at. I specifically chose calcium in my example to be anything other than Alk to try and get people back to thinking how they normally would handle a change. The KHD should not be the "doser" for Alk and I don't believe it was ever intended to suit that purpose. It has the ability to dose to make incremental corrections when the dosing program is falling short, or shooting off the charts. It should be used to notify the reefer that there is a problem and fix make a TEMPORARY fix to mitigate catastrophe. I honestly believe there are going to be people that are going to start complaining that the KHD caused their calcium and magnesium to go off the charts. When we ask what happened they are going to show us that their Alk had dropped by a point and a half and they had the KHD make the correction to the Alk and then programmatically propagated the same "increases" across the other balling doses.
