What one dose does
PARAMETER
1 ml / 100 L
Alkalinity
+0.0531 dKH
To raise alkalinity by 1 dKH in 100 L: 18.8 ml.
Maker’s daily maximum: 26.4 ml per 100 L (26.4 ml for 100 L).
How it’s used
Start 5 ml (1 tsp) of each part per 25 US gal per day (another label section says per 20 gal), dosed separately into strong flow. Adjust by testing; keep alk 2.5-3.5 meq/L. Max 1 ml/gal/day per part, split into 2+ doses (max 1 ml per 2 gal at once).
Cautions
• Max 1 ml of each part per US gal per day; exceeding can push pH too high
• Never mix A and B or store them with other supplements
• Part B may cloud the water briefly and can crystallise below room temperature (redissolves above ~75 F)
• 1-gal size is a concentrate: top off with RO/DI before use
