Swimming pools, whether public or private, can be the source of the proliferation of various skin diseases or infections, such as fungi, warts or fungal infections. It is to limit this proliferation that several products are used. These come in a liquid form or a tablet form, and each of them has a distinct utility:chlorine, bleach and a Ph adjuster. Pool owners must comply with the dosages required by law , because they are subject to rigorous monthly health checks by the competent ARS or Regional Health Agency.
The pool owner must first ensure that his pool is always well cleaned, whether on the surface or at the level of its filters. These should be cleaned as often as possible because hair and other residue or dirt can cling to them and clog them. The water would therefore risk no longer being filtered properly, and bacteria could grow freely. Then, the disinfectant products mixed with the pool water must respect the dosage established by the regulations in force, and following the recommendations of the Mag de la piscine, namely no more than 0.6mg of chlorine per liter of water, and a Ph between 6.9 and 7.7. Moreover, these dosages are always indicated on the packaging of the products in question. The risk of not putting enough products is that the water will not be properly disinfected, and conversely if there are too many products it would represent a danger for the skin and the health of bathers. Indeed, for example too much chlorine dries the skin which will end up tight and become reddish, then will strongly irritate the eyes and the nose. It is to avoid all these inconveniences that the ARS mentioned above carries out mandatory bacterial tests (see here all the good things to do to maintain your swimming pool).
As a preventive measure, it is mandatory to wash with soapy water before swimming to remove all dirt that could attract bacteria present in the pool water, while possibly avoiding contaminating other bathers. Indeed, without knowing it, you may already be a vector of bacteria that will spread in the pool. Once swimming is finished, it is strongly recommended to wash thoroughly again with soap or shower gel. After taking this shower, for more precautions, it is better to wash with a special product to fight fungus. Indeed, these proliferate very quickly and it is always easier to prevent them than to cure them. The quantity of revivable germs and coliforms are subject to tests for this purpose, but their percentage will only be checked monthly, and despite the addition of several liters of new water to the pool daily. Finally, apply a moisturizer to avoid the drying effects of chlorine.
