7.1.3.1.Filtration
The water in your pool is pumped through a filter to remove debris and particles. How long you need to run the filter depends on the size of your swimming pool and the horsepower of your pool pump. If you are unsure, check your instruction manual or consult with a pool maintenance company. Remember that even when you are filtering your pool according to specifications, about 35 per cent of the water still won't be filtered.
