You should aim to keep the chlorine level at between 1 and 3 ppm.
We suggest shocking the pool every week to two weeks; with hot weather or increased use, you may need to shock more often.
When tabs run out, replace them.
Is it better to put chlorine in a pool in the morning or at night?
t’s best to add chlorine to your pool at night, so it can work while no one is swimming and the sun has set. If you use a slow-dissolve chlorine treatment like a tab, adding it at night gives it time to dissolve, so the pool will be ready to face the day.
