To raise alkalinity by 1 dKH in 100 L: 37.5 ml.
297 g (about 1 1/8 cups) unbaked NaHCO3 to 1 US gal -> ~950 meq/L (2,660 dKH) published; stoichiometric 297/84.01/3.785 L = 934 meq/L.
• Keep alkalinity increases <=1.4 dKH/day (BRS).
• Never premix with the calcium part.
• Slow to dissolve at ~1 cup per gallon; warming helps (do not boil - converts toward carbonate).
297 g made up to 1 US gal total.
