Regular (fortnightly) superchlorination with Shock breaks down chloramines which are formed when chlorine links to nitrogen compounds introduced by bathers - these are responsible for so-called 'swimming pool smell'. Pools should also be shocked on first signs of water turning green as unstabilised chlorines such as Fi-Chem Shock are extremely effective at killing algae fast. As with Fi-CLOR Granules, the particle size is tightly controlled to assist quick dissolving.
