So I'm mixing up some mag and the instructions on the newer mag chloride container only show one mix ratio, but on my older container of mag sulfate it shows 2 different mixes. One for regular 2 part dosing and the other for kalk. I checked on the brs website and all I see is the 2 part formula, but I also see they sell an all in one kalk mag mix as well as a reg mag mix. What do I do??
