What one dose does
PARAMETER
1 g / 100 L
Alkalinity
+0.3333 dKH
To raise alkalinity by 1 dKH in 100 L: 3 g.
How it’s used
Mix 302 g per 1 US gal final volume. Use for big alk corrections or daily dosing in high-pH tanks; dose 5-day calculator amount /5 daily and adjust +/-10%/day. Pair with half-strength CaCl2 (4.9 ppm/ml/gal) for 1:1 volumes.
Cautions
• Raise alk no more than 0.5 meq/L (1.4 dKH) per day
• Slightly lowers pH temporarily
• Half the strength of soda ash solution: double the volume for the same alk

Sources
maxDose derived from BRS limit of 0.5 meq/L per day (0.5/0.25). BRS worked example: 214.2 ml over 5 days raises 100 gal by 1.5 dKH (= 0.70 dKH per ml/gal), consistent.
