Pool, which comes from piscīna (a Latin word), is an artificial reservoir of water that is used for recreational, sporting or decorative purposes. Known in some countries as a swimming pool or swimming pool, the pool allows people to cool off in the summer, practice swimming or play water games, among other activities.
For example: "In a while I will go to the club pool" , "My dream is to have a house with a pool" , "Unfortunately the pool is not full, so we will not be able to cool off even if it is so hot" .
However, it should not be forgotten either that there are natural pools scattered all over the world. Thus they have great beauty and allow people to take a bath in the middle of the environment. Among the best known are the Spanish ones from Sierra de Gata, in Cáceres.
Since Roman times, man has designed various water reservoirs to take advantage of its benefits without having to resort to rivers, lakes, oceans or other natural means. The pools can have very different characteristics and sizes, according to the available space and their purpose.
In private homes, it is possible to find removable pools that are only set up in the summer. These are small pools, usually made of polyester. Some houses, however, have stable pools whose structure is buried.
Sports clubs, for their part, usually have large pools so that many people can use them simultaneously. When the pool has some kind of roof or cover and the water temperature can be regulated, it is called a heated pool.
Typically, pools are chlorinated to purify the water and prevent the proliferation of bacteria and insects in the water. It is important to control certain parameters and amounts when adding chlorine to the pool water: otherwise people may suffer from burning eyes and other discomfort.
However, it should not be overlooked that, in recent years, in order to ensure that water is in perfect condition to be used and that it does not harm people's health, the demand for what is known has grown as salt chlorination. This is a pool water maintenance technique that is based not on the use of chlorine but on salt, as if it were the sea.
This salt, after going through a current circuit and the so-called electrolysis occurs, brings with it that the water is in perfect condition.
If this system has experienced remarkable growth, in terms of demand, it is because it brings with it a significant number of benefits:
-It does not cause red eye problems in people, as it does chlorine.
-It is more respectful with the environment.
-Avoid the use of chemical products.
-It is very comfortable, since it hardly requires maintenance and works for several years.
-It is a much cheaper alternative.
-Aesthetically, the water looks much better.
-It seems that in the pools where saline chlorination is applied there are no problems with wasps or bees.
