Swimming in crystal-clear water, without any
chemical additives, is a wonderfully refreshing experience.
Nature does the work for us: next to the pool
is a filtering basin filled with lava stones and gravel in
which various plants grow that clean the water naturally day
and night to ensure that the water in the pool is transparent
and hygienic. We do not use chemical products such as chlorine,
salt or other products that could irritate the skin and eyes.
It is nature itself that cleans the water. The stones heat
up in the sunshine and at night they transmit the heat accumulated
during the day to the water. This means that the water is
at a pleasant temperature even in springtime. What is more,
tiny fish live in the filtering pool, thus keeping the water
free from insects.
