What one dose does
PARAMETER
1 ml / 100 L
Calcium
+0.9464 ppm
To raise calcium by 20 ppm in 100 L: 21.1 ml.
How it’s used
1-2 capfuls (7-14 ml) per 50 US gal once or twice a week; test calcium and adjust.
Cautions
• Contains organic calcium salts (propionate, succinate, gluconate) - adds organic load
• Contains a pH buffer
Sources
Blend of calcium chloride + organic calcium salts with vitamin D. Very low-dose routine (+3.5-7 ppm per 50 gal weekly) - a maintenance top-up, not a correction product. The ARKA relabel page also claims 'over 450 mg/L of calcium', which contradicts its own 5 mg/L-per-5 ml/100 L dose (would need ~100 g/L); treated as a typo.
