Pool Chlorine - Spa Chlorine

Chlorine is the most commonly used sanitising agent to keep your pool or spa fresh and clean by breaking down impurities and bacteria. For healthy bathing, chlorine needs to be added until it is present as 'free chlorine'. This is the stage reached after all the impurities have been broken down and further chlorine has been added. Ideally, the amount of free chlorine should never fall below 1 part per million (ppm). For most private pools, we recommend a free chlorine level of between 1 and 1.5 ppm. For larger, frequently used pools, we recommend 2 to 3 ppm. Read more about using chlorine in our chlorine help guides seciton.
