What one dose does
PARAMETER
1 g / 100 L
Strontium
+5.4131 ppm
To raise strontium by 1 ppm in 100 L: 0.18 g.
Maker’s daily maximum: 0.11 g per 100 L (0.11 g for 100 L).
How it’s used
Dissolve first. Basic: 1 g (~1/4 tsp) per 40 US gal in 8 fl oz fresh water every other day for 8-12 ppm. Advanced: use a stock solution and dose to replace measured daily loss.
Sources
CONFLICT: page says stock of 2 g in 8 fl oz gives 0.75 ppm per ml per US gal, but 2 g / 236.6 ml x 143 ppm/g = 1.21 ppm per ml. The per-gram figure (143) matches the guaranteed analysis, so it is stored; the stock-solution figure looks wrong. maxDose derived from stock limit (10 ml of 2 g/8 fl oz stock per 20 US gal = 0.085 g).
