Dosing
The maker doses this by schedule rather than by a fixed potency, so the calculator cannot use it. Follow the directions below.
How it’s used
ESV lists strontium as a weekly additive dosed to test results; no label dose found.
Cautions
• Can slowly depress alkalinity like calcium chloride
• Potency unknown: hydrate basis of the 20% figure not stated
Sources
Missing: hydrate basis of '20%'. If 20% w/v SrCl2.6H2O: 65.7 g Sr/L -> 1 ml in 100 L = 0.657 ppm Sr. If 20% w/v anhydrous SrCl2: 111.0 g/L -> 1.11 ppm. The 1.7x spread is too large to pick one, so effects left empty. Possibly later sold as 'B-Ionic Strontium'.
