Is chlorine for the pool necessary?
The disinfection of swimming pool water in which people bathe is a treatment aimed at purifying the water . It is not just about crystallisation or hygiene, but about our health. Water that is not disinfected has thousands of bacteria and micro-organisms in it, which significantly affect our health. So it is easy to conclude that chlorine disinfection is essential in any tank.
Filtration alone is not enough to keep the water in good condition. Some people claim that salt water is enough as a solution to nullify bacteria and micro organisms. This is not entirely true. The fact is that salt is used, but it has to be broken down into chlorine and sodium by electrolysis.
