Cool Calculator!
Gotta play with it...
For a 20 gallon tank, it says that if you add 4 grams calcium chloride and 1 gram mag sulfate that will result in 21.15 ppm calcium and 1.3 ppm magnesium.
To get a 4 to 1 ratio of ca to mg in ppm you'd add equal amounts of calcium chloride and mag sulfate.
to get a 1 to 1 ratio of ca to mg in ppm you'd need to add 1 part calcium chloride to 4 parts mag sulfate.
