Filtration circulates the water in the swimming pool and filters solid impurities. A correctly sized filtration system is essential (pump flow, filter size, etc).
This initial treatment covers about 80% of maintenance effectiveness.
Note that the filtration time is proportional to the temperature.
As the temperature increases, the filtration time necessary also increases. The table below will help you choose the suitable filtration time.
Filtered water looks clean and pleasant but it can still contain invisible particles. The best filtration system cannot deal with micro organisms: algae, bacteria, viruses, mould, etc.
Pool water thus requires additional treatment: disinfection.
