What one dose does
PARAMETER
1 ml / 100 L
Calcium
+1.4006 ppm
Strontium
+0.0273 ppm
To raise calcium by 20 ppm in 100 L: 14.3 ml.
Maker’s daily maximum: 8.8 ml per 100 L (8.8 ml for 100 L).
How it’s used
Shake well; dose at night (may cloud). Basic: 5 ml per 50 US gal every other day for 412-450 ppm. If below 412 ppm, up to 10 ml per 30 US gal daily. Maintenance ml/day = daily Ca drop / 37 x US gal.
Cautions
• May temporarily cloud water; dose at night.
• May irritate eyes/skin.
Sources
Aragonite suspension plus Ca/Sr/Mg/K salts. Guaranteed carbonate 104,800 ppm (as CO3) would imply up to ~2.6 dKH per ml per gal if fully dissolved, but Brightwell claims no alkalinity effect and the aragonite is particulate, so no alk effect is stored.
