Should I use liquid or granular chlorine?

01 January 2017

It depends on a couple of factors. Liquid chlorine (also known as Sodium Hypochlorite) is one of the easiest forms of chlorine to use, as there's no need for premixing. It has a limited shelf life so it shouldn't be purchased too far in advance.

Granular chlorine, on the other hand, needs to be dissolved in a bucket of water before being added to your pool. Its pH is not as high as that of liquid chlorine but it still has a tendency to lift your pH. Because of the 35% calcium content in this type of chlorine it can have the effect of lifting your calcium hardness level.

TIP: Liquid chlorine is easy to use and requires no pre-mixing.

TIP: Granular chlorine must be mixed in a bucket with water.
