I converted to Beersmith 4 recently and I have noticed that when I ask it to match a water profile it is suggesting magnesium chloride as a brewing salt addition. I never saw this in Beersmith 3 and I do not have magnesium chloride and haven't seen it commonly mentioned in water profiles before. I can delete it and balance things our using Epsom salt (MgSO4) but it is a bit of extra work. I tried deleting magnesium chloride from the Misc ingredients with success but the water profile tool continues to suggest magnesium chloride. Any hints or am I just stuck deleting it from the suggest salt additions?
