AIS chlorinators automatically disinfect your pool or spa water generally meaning an end to manual chlorine dosing [i], however from time to time it may be necessary to add some additional chlorine to your pool. This may be due to heavy rainfall events, excessive bather numbers or weather events – for instance after a storm when there is lots of organic matter (e.g. leaves) in the pool.
Should you need additional chlorine for your pool, AIS recommends the use of liquid chlorine.
Granular chlorine is not recommended as it can leave calcium behind which in turn can create cloudiness in the pool as well as increase ongoing maintenance requirements. For safety reasons, in the case of using granular chlorine, ALWAYS dissolve the chlorine first in a bucket reserved only for chlorine use (i.e one never used for other chemicals) and ALWAYS put the water in the bucket first, followed by the chlorine.
