Active Oxygen

Active Oxygen is an alternative pool water treatment method to the established Chlorine or Bromine based systems. Although compatible with Chlorine and Bromine systems (and often used in conjunction), Active Oxygen is based on the strong oxidiser Potassium Monopersulphate.

It is sometimes used in private pools with an algicide to aid disinfection. In public pools it is mainly used as an alternative to Chlorine when shock dosing is required, as Potassium Monopersulphate will break down organic chloramines more effectively than Chlorine based disinfectants.
