Pool water contains several elements: calcium, magnesium, sodium, sulphates, etc...
These elements must remain balanced.
In a swimming pool, this balance will be upset by various factors:
- Organic waste brought by swimmers (sweat, perspiration, saliva, urine, beauty products, sun cream, etc) and other wastes coming from the outside environment (dust, pollen, insects, leaves, etc). All of this waste is the food of micro organisms.
- Micro organisms: Algae, moss, bacteria, mushrooms, viruses, etc
For this reason, swimming pool water that is not maintained will stagnate (green or cloudy water, development of algae, etc). This is a visual result and indication of the development of micro organisms.
