Pool maintenance

How often does the water have to be changed?

You do not actually have to change the water in an outdoor pool because it is completely renewed by rainwater every 1.5 years. A 4x8 metre pool holds 37,500 litres of water. With the average annual rainfall in Germany, 25,000 litres of rainwater are fed into the pool every year. In 1.5 years, the pool contents are completely renewed once. It is assumed that the basins will no longer become as polluted in winter as they were years ago when there were no roller shutter covers or winter leaf nets. Thus, at the beginning of the season, it only needs a fraction of care, and as described above, it will simply always remain in the pool.

With an indoor swimming pool, things are naturally somewhat different. Freshwater must be continuously supplied simply to compensate for evaporation. Every three to five years, the water should be completely changed because the chloride content in the water also increases over time.
