People often think mistakenly that a strong smell of chlorine is because too much disinfectant has been used.

Whereas insufficient chlorine encourages the development of chloramines, which is a result of this chlorine oxidising organic materials that generally come from the swimmer (hair, dead skin, saliva, urine, sweat, etc.).

Chloramines are not only smelly but are also strongly irritate the eyes and throat.

If your pool has a cover, open it to provide ventilation.

Adjust the pH to between 7.0 and 7.2, with hth®  pH PLUS POWDER to increase the level or hth®  pH MINUS MICRO-BALLS to reduce it.

Perform a shock chlorination treatment  with hth®  SHOCK® Powder (continuous filtration operating). You should then wait 48 hours before using the pool.

   Did you know?

Chloramines are produced by the reaction between chlorine (in the form of hypochlorous acid HOCl) and ammonia (NH3). 

They represent a much greater health risk than active chlorine.
