Quels sont les inconvénients d'une piscine au sel ?

Salt electrolysis has many qualities and provides a appreciated service, but it should be noted that this system has certain constraints that must be taken into account. First and foremost, the cost of purchasing the device. Although, in use, salt electrolysis is financially very advantageous since no other additional product is needed; the initial investment is significant. In addition to special salt and the device with its installation, it is highly recommended to install an automatic pH regulator. Indeed, the sodium hydroxide produced for water disinfection significantly affects the pH. Furthermore, if the pool is covered by a shelter, a safety cover, or a cover, it is advisable to install a Redox control. It measures and limits the chlorine level. Indeed, when the pool is covered, the chlorine remains "trapped" and becomes corrosive. Redox control prevents overproduction of disinfectant, which leads to degradation of the pool lining and equipment. Regarding the submerged cover, a pool ground must be installed to limit oxidation and capture stray currents. In addition, the winding axis must be composite, as most submerged cover manufacturers limit or even cancel the warranty if the treatment is salt-based and the cover axis is made of 316L stainless steel or anodized aluminum. The cell is essential for the operation of the device. If it is dirty or scaled, electrolysis cannot perform its function. Therefore, it must be cleaned regularly or an electrolysis with self-cleaning by polarity inversion must be purchased. In any case, it needs to be replaced after a few years of service, costing between 200 and 500 euros. Salt electrolysis does not tolerate cold water. Therefore, the device must be restarted or winterized when the water reaches 12/15°C (depending on the models). If swimming is planned all year round, a pool heat pump will be necessary. Pool water is less salty than seawater. The amount of salt present in a pool treated by salt electrolysis is low, between 3 and 7 grams per liter. However, the slightly salty taste may cause discomfort for some people. Salt electrolysis is a device that facilitates pool water treatment, relieves the homeowner of a number of tasks, and improves bathing quality. However, certain checks and cleaning of the pool should not be overlooked for proper equipment operation.

Le traitement d'une piscine au sel comporte toutefois certaines contraintes, notamment : Niveau de pH de l'eau augmenté : Le traitement au sel a tendance à faire grimper le taux de pH, si bien que le propriétaire doit suivre régulièrement son niveau pour l'adapter en cas de besoin ou, pour plus de tranquillité, se doter d'un régulateur de pH. Matériels corrodés : Le sel est corrosif et s'attaque à l'électrolyseur prématurément s'il n'est pas auto-nettoyant ou lavé fréquemment. L'appareil doit en principe être arrêté lorsque la température de l'eau est inférieure à 16 degrés, en effet en dessous de cette température, la résistance de l'eau à l’électricité est plus forte et il y a donc potentiellement une usure prématurée des électrodes. Coût plus élevé : Le traitement d'une piscine par électrolyse au sel a un coût de revient en général un peu plus important par rapport aux méthodes au chlore ou au brome. Si le prix de la matière première est bien moindre, c'est l'achat et l'installation de l'électrolyseur, en moyenne de 1 500 euros, qui sont onéreux. Le fait que l'eau soit salée peut enfin constituer un désagrément pour certains baigneurs, mais le goût est extrêmement léger et n'est en rien comparable avec celui de l'eau de mer.
