The ideal range for chlorine in pool water is 1-3 ppm, so you should aim to maintain this on a weekly basis. Exactly how much swimming pool chlorine you’ll require and how often you’ll need to re-dose your pool will depend on several factors, including the size of your pool and the frequency of use.
If you have a larger pool, liquid chlorine may be the better option for you. Liquid chlorine pool chemicals can also provide effective shock treatments as they’re fast-acting and can be easily added to your water.
To find out more about using chlorine shock, whether it’s liquid or granules, see our guide to swimming pool shock treatments.
