I forgot about the cost factor between C-balance and B-ionic:

C-balance:

Part A: 1ml/gallon is required to raise Ca by 10ppm
Part B: 0.7ml/gallon is required to raise Alk by 1dKh

B-Ionic:

Part A: 2.5ml/gallon is required to raise Ca by 10ppm
Part B: 1.9ml/gallon is required to raise Alk by 1dkh

So from the above dosing requirements, it is quite clear that C-balance, with its concentration, is actually almost half the cost of B-ionic.
