I agree Wasp,
My philosophy is to chuck heaps of MaG, Ca, and Strontium Chloride in to the tank all the time. I also throw in a tablespoon of MG sulphate every now and again, but I do large 30% water changes every six odd weeks.
This is the balancing regime I believe works for my system. I have been doing it for 2 years and my tank is ok.
Chim.....Maybe a year too much, but find me proof of disaster WITH Chloride overdose first.
