Because if that amount of grams are not maintained, there will either more be more sodium ions or more chloride ions with an end result of being imbalance.

And here is your answer in probably more detail than you could ever wish for
Hans-Werner does not hold back
• Sodium chloride has a molar weight of 58.44 g/mol.
• In 2 l of R/O water a max. of 2 mol sodium bicarbonate can be dissolved. After addition of 2 mol sodium bicarbonate and 1 mol calcium chloride 2 mol sodium chloride remain in the aquarium. 2 mol sodium chloride can be balanced with exactly 50 g of sodium chloride free sea salt.
• Formula:
CaCl2 x 2 H2O + 2 NaHCO3
CaCO3 + 2 NaCl + CO2 + 3 H2O
• Insert weights:
147 g CaCl2 x 2 H2O + 168 g NaHCO3 100 g CaCO3 + 117 g NaCl + 44 g CO2 + 54 g H2O
117 g NaCl + 50 g NaCl free sea salt 167 g complete sea salt
• Adjust tank water to 7° KH and 420 ppm calcium.
• Check alkalinity after two days. Calculate how much alkalinity solution is needed. Add same volume of all three solutions.
• Continue with daily additions of half the volume.
• Adjust added volumes to keep 7° KH alkalinity.
