Strong Chlorine Odour (chloramines/combined chlorine present)

  • When water smells like chlorine, oxidation is required since the odour is a sign that nitrogen is present (ammonia odour), which gives off a chlorine-like smell.
  • These ‘Chloramines’ are most often the result of organic wastes (unfiltered materials) generated by bathers and include: perspiration, urine, sunscreen, deodorant, fecal matter from diapers etc., nasal and other discharges, as well as nitrogen residue.
  • Chloramines cause burning eyes, a strong chlorine odour and taste, and may cause skin irritation.
  • Chloramines can only be eliminated with a shock treatment.


  • Use S.W.A.T.


  • Always shock after a pool party, heavy rain or extremely hot weather.
