What one dose does
PARAMETER
1 ml / 100 L
Calcium
+1 ppm
To raise calcium by 20 ppm in 100 L: 20 ml.
How it’s used
Dose the same volume as #1 (3-7 ml per 100 L/day guideline). If Ca drifts over a week, set #2 from Ca use: 1 ml/100 L/day per 1 mg/L daily Ca loss.
Cautions
• Dose #1 and #2 at separate, well-flowing spots; never mix the two parts outside the tank
• #1 can crystallize when cold: warm bottle to ~45 C; below 20 C dilute both parts 1:1 with RO so volumes stay equal
• Long-term use slowly raises salinity: periodically swap a little tank water for RO
