Do I need to shock treat my swimming pool?
You may need to shock treat your swimming pool. If the chemical balance of the pool water is correct and there are no filtration problems (clogged filter, sand needs replacing, filter needs backwashing), then cloudy pool water or dull water may be corrected with a flocculant. In the event that this fails to clear the pool water, you can try a shock treatment. Algae growth may also need a shock treatment.
