Damn Jayrug,

That's a hard question. But I think I can help ya out a little ..

about one gram of mixed calcium chloride and magnesium sulfate (mixed 6:7 by weight) will raise 10 gallons of water by 1 degree general hardness (1 dGH) and provide an ideal calcium to magnesium ratio (3:1)

by Kevin Zippel, Ph.D
So, you need 2.54 grams of CaCL2 & 2.96 grams of MgSO4 to raise 55 gallons 1dgh.

I use 3:1 for my tank and it hasn't cause any issues.

Good Luck
