What one dose does
PARAMETER
1 ml / 100 L
Calcium
+1.3236 ppm
To raise calcium by 20 ppm in 100 L: 15.1 ml.
How it’s used
Shake hard. Add by hand at night in strong flow: 1 capful (5 ml) per 50 US gal 3-4 times a week (daily preferred), or size doses to Ca consumption with the 0.0286 ml per gal per ppm factor. Test Ca and adjust.
Cautions
• Clouds the water temporarily: add at night near strong flow
• Not suited to most dosing pumps (needs agitation)
• Do not premix with other supplements
Sources
Suspension of powdered marine aragonite plus mineral salts, sold as a one-step calcium + carbonate 'reactor in a bottle'. Label routine dose reads '50 US-gallons (100 L)' (50 gal is ~189 L) - inconsistent. If it were pure dissolving aragonite, 10 ppm Ca would bring ~0.5 meq/L (~1.4 dKH) of alkalinity, but the maker publishes no alk figure, so none is recorded.
