Swimming pools provide a great deal of enjoyment. But they do collect dirt, leaves, grass, bugs and debris. So, to maximize the enjoyment of the swimming pool does require some maintenance.
Swimmers contribute to the “contaminants” in swimming pool water, such as hair, skin oils and bodily secretions/fluids, including urine. All of these contaminants create a chlorine demand. Reducing these contaminants will help to minimize the amount of chlorine needed to keep your pool properly sanitized. Having a shower for swimmers to use before getting into the pool will help by reducing dirt, suntan products and body oils.
Most all swimming pools are equipped with filtration equipment. Filters should be checked frequently. Some filters can be cleaned by backwashing; others are equipped with a debris bag which can be replaced as needed; and others have a filter cartridge which can be cleaned or replaced.
Pool side walls should be checked frequently for any build-up. If the pool pH rises outside of the recommended ranges, calcium may build up on pool side walls, ladders, pumps and pool decks. This is another reason why pH control is an essential part of pool maintenance.
Pool bottoms should be vacuumed regularly to remove accumulations of debris.
One of the major factors that determine swimming pool water quality is the source of the water used to fill the pool and the water that is added periodically to keep the pool at the correct water level.
Most public or municipal water systems in the United States are required to meet U.S. Public Health Standards. In general, water from a public water system will provide a good source to fill a swimming pool and to add water to compensate for water lost due to evaporation or filter backwashing.
Water obtained from groundwater wells or surface waters like lakes or rivers will require testing to determine its suitability as a pool water source.
Waters which contain dissolved organic material which cause the water to be brownish (similar in appearance to weak iced tea) can become a problem when chlorine is added. Chlorinated organics can create a series of chemicals know as disinfection by-products. Disinfection by-products can be harmful if ingested. (6)
Care should be taken in choosing the source of water for swimming pools as ultimately it will have an effect on pool water quality and pool maintenance.
Some people use a liquid chlorine bleach storage tank and a small chemical pump to pump chlorine into the swimming pool. This can add to maintenance requirements because the liquid chlorine bleach level in the storage tank needs to be checked and the pump and tubing must be checked frequently.
The manual addition of liquid chlorine bleach is the most widely used and recommended method of chlorinating residential swimming pools and it provides the owner an opportunity to become familiar with the workings of the pool and to develop a hands-on understanding of how the chlorine and pH levels of the pool are affected by weather, temperature and varying usage levels.
Care should be taken in the storage and handling of liquid chlorine bleach and the acid used for pH control. The liquid chlorine bleach and acid should be stored separately and the user should read and observe the directions for use and precautions on the product labels.
If liquid chlorine bleach is used as a manually added sanitizer there is no maintenance required because there is no equipment necessary to manually pour liquid chlorine bleach into the pool.
