Dosing and Feeding

  • Continuous dosing 1 to 2 ppm free chlorine, for periods longer than 12 hours a log 6 reduction is observed.
  • Shock dosing 5 ppm free chlorine, 2 hours contact time (using European Standard Test).
  • A comparator test kit is available to determine correct levels of chlorine in the system (WTP TK115).


Use biocides safely. Always read the label and product information before use. Add chlorine tablets to floating dispenser, skimmer basket or automatic feeder to maintain the chlorine levels at 1-2 mg/litre (ppm).
