What one dose does
PARAMETER
1 g / 100 L
Alkalinity
+0.3505 dKH
To raise alkalinity by 1 dKH in 100 L: 2.9 g.
Maker’s daily maximum: 8 g per 100 L (8 g for 100 L).
How it’s used
Beginner: 3 g (1/2 level tsp) per 150 L (40 US gal) twice a week, dissolved in >=250 ml fresh water. Raise toward 3-6 meq/L (8-17 dKH). Drip formula: grams = 0.08 x liters x meq/L rise. Max 12 g per 150 L per day.
Cautions
• Excess alkalinity can precipitate calcium, magnesium and strontium.
• Do not mix directly with Ca/Mg/Sr supplements; dose on alternate days or >=30 min apart.
Sources
Carbonate blend that raises alkalinity with minimal immediate pH impact (trends to pH 8.3).
