I did and do it sometimes, usually check pH and SG. If I'm starting a new bucket of salt I'll test Ca, Alk, Mg just to see if it's another one of those bad bunches but after the first batch of make up it's just pH and SG. I'll adjust Ca, Alk the same way for each batch of make up water. 1ml of Ca, 1ml of Alk and I add my Mg suppliment (Kent Tech M) once a week to my freshwater top off.
