Calcium
+0.6057 ppm
To raise calcium by 20 ppm in 100 L: 33 ml.
Maker’s daily maximum: 26.4 ml per 100 L (26.4 ml for 100 L).
How it’s used
Dose in equal volume with Component 1: start 1 ml per 4 US gal per day (1 ml per 8 gal with kalkwasser), test Ca and alk often and adjust. Also supplies Mg and seawater trace ions in proportion.
Cautions
• Do not exceed 1 ml per US gal per 24 h
• Never combine with Component 1 before it reaches the tank
• Concentrate sizes must be diluted to the fill line

Internal inconsistency on the label: 54,000 ppm Ca implies ~14.3 ppm per ml/gal, but the stated effect is 16 ppm. Using the stated 16 ppm (also the BRS calculator constant). Balanced against Part 1: 16 ppm Ca = 0.80 meq/L vs 0.74 meq/L alk.
