What one dose does
PARAMETER
1 ml / 100 L
Potassium
+1.75 ppm
To raise potassium by 20 ppm in 100 L: 11.4 ml.
Maker’s daily maximum: 5.7 ml per 100 L (5.7 ml for 100 L).
How it’s used
Dose daily at 1 ml per 100 L for every 20 ppm of Ca consumed (1 ml per 10 ml of Calcium+), or to measured potassium uptake using the 4-day test method. Test Ca or K weekly.
Cautions
• Max daily rise: iodine 0.03 ppm, potassium 10 ppm, iron 0.05 ppm
• Overdose: change 50% of the water (25% for Potassium+) and cut the dose by 50%
• Many trace elements are toxic above natural seawater levels; dose only to measured demand

maxDose derived: 10 ppm/day K limit / 1.75 = 5.7 ml per 100 L/day. Red Sea target (NSW): K 400 ppm, B 4.6 ppm.
