Swimming Pool Water

Swimming pool water must maintain low levels of bacteria and viruses to prevent the spread of diseases and pathogens. Bacteria, algae and insect larvae can enter the pool if water is not properly sanitised.
Pumps, mechanical filters, and disinfectants are often used to sanitise the water.
Chemical disinfectants, such as chlorine (usually as a hypochlorite salt, such as calcium hypochlorite) and bromine, are commonly used to kill pathogens.
If not properly maintained, chemical sanitation can produce high levels of disinfection byproducts.
Sanitised swimming pool water can theoretically appear green if a certain amount of iron salts (Copper Chloride) are present in the water.
The benefit of using a sat chlorination system far outweigh any other method. It enhances the lifespan of any pool especially in the case of fibreglass linings. There is also limited “red eye effect”, and the salt is far healthier for the body and swimming costumes.
