What one dose does
PARAMETER
1 g / 100 L
Alkalinity
+0.3142 dKH
To raise alkalinity by 1 dKH in 100 L: 3.2 g.
Maker’s daily maximum: 1.7 g per 100 L (1.7 g for 100 L).
How it’s used
Make a stock (basic 20 g, advanced 30 g per 8 fl oz purified water; max 58.3 g) and dose to hold 7-12 dKH with Reef Code A-P. Grams needed = dKH rise x US gal / 8.3.
Cautions
• Never mix A-P and B-P solutions.
• Contains carbonate/bicarbonate; harmful if swallowed.

CONFLICT: 30 g/8 fl oz stock is said to give ~1.0 dKH per ml per gal (30/236.6 x 8.3 = 1.05, consistent), yet the maintenance instruction says divide the daily dKH drop by 2.1, which would double-underdose. Also 8.3 dKH vs '3 meq/L' (8.3 dKH = 2.96 meq/L, fine). Stored the per-gram value. maxDose derived from stock limit (10 ml of 30 g/8 fl oz per 20 US gal = 1.27 g).
