During the winter, there is a reduction in the use of swimming pool the same time as the temperatura decreases, especially those located outdoors. For this reason, it is important to make a correct maintenance of the swimming pool and get it ready for the starting of the next bathing season, protecting both health and environment.

Hibernation is one of the most advisable, economic and eco-conscious options. It consists on keeping the water in good conditions during the winter, in order to be reused at the beginning of the warmest months of the year.

The main points are:

1. General cleaning of the pool, rubbing of walls and cleaning the pool bottom. Always remember cleaning the filter of the pump and the skimmer baskets

2. Analysis of the wáter pH in order to keep it between 7.2 and 7.4. This will prevent the appearance of algae and the most important matter, will ensure that the skin of bathers does not suffer any type of irritation.

3. Chlorination of the pool: it will be necessary to keep the filter working around 6 hours in order to homogenize the products. The following day, it is necessary to clean the filter.  This process helps to avoid decomposition, especially in case the pool is next to vegetation.

For those pools which have salt electrolysis systems for the treatment of water, there is a different previous treatment to be applied.

If the temperature of the water is higher than 15ºC, the equipment must be left running long enough to maintain a chlorine residual of between 0.5 and 1.0 ppm, adjusting the pH between 7.2-7.4. manual or automatically.

In case the temperature of the water is below 15 ° C, the electrolysis equipment must be switched off, and the chlorine generating cell extracted, to clean it with electrolytic cell descaler and in this way eliminate the possible incrustations.

In case there is a pH or pH / Rx control and regulation equipment, pH and RedOx electrodes should be carefully removed, and placed in a preservative solution, in the original cover or in a dry place between 10ºC and 30ºC, verifying that the pH and Redox electrodes have the final end inside the factory original liquid of the preservative solution, being essential that the Protective case is always moistened with this solution.
