Running the filter after shocking for 24 hours to 7 days is necessary if the pool has a large amount of algae.
Does chlorine increase pH?
Using liquid chlorine raises the pH of the water. Liquid chlorine does not raise pH. When added to water, liquid chlorine (which has a pH of 13) makes HOCl (hypochlorous acid – the killing form of chlorine) and NaOH (sodium hydroxide), which raises pH. So the net effect on pH is zero (or almost zero).
Do I add chlorine everyday?
A chlorine level of between 3-5mg/l must be maintained in your hot tub at all times. The addition of chlorine will depend upon usage and bathing habits. It could be daily or every 2-3 days (for 1mg/l add 2g per 1000 litres).
