Swimming pools need different water treatments to keep them clean and usable. Water treatment prevents the buildup of unwanted elements in the pool water. Some of these treatments can be antimicrobial or antifungal. There are many types of water treatment for pools. Listed below are some examples.

Chlorinators

Chlorine may be the most widely used chemical for swimming pool water treatment. Handling powdered chlorine can be dangerous, so pool equipment designers made chlorinators. Chlorinators are devices that feed chlorine solutions into swimming pools through a series of hoses. Most chlorinators can be programmed to automatically chlorinate pools. These kinds of water treatment of swimming pools are effective in killing water-living microorganisms. A chlorinator costs around $250.

Testing kits

Testing kits maintain a balanced water chemistry that is essential for keeping swimming pools clean. Pool cleaners can determine water pH levels, chlorination, oxidation, and the presence of other chemicals in pool water. These testing kits include several kinds of chemicals and test tubes. Pool water is extracted and placed in a tube, and the diagnostic chemicals are placed in the tube of water. The waters reactions to these diagnostic chemicals, determines its chemical content. While these kits are helpful, they do not directly clean pool water. A testing kit usually costs $50.

There are electronic versions of the testing kits. Water is placed inside a chamber of the electronic apparatus for testing. Water treatment of swimming pools that use these electronic kits can test only for water pH levels. It costs around $70.

Swimming pool hard water treatment

The following treatments are effective as swimming pool hard water treatments. Hard water means water with high mineral content. Minerals and particulates from pool-cleaning agents are common in most pools, but high concentrations of these can be potentially harmful.

Erosion feeders

Erosion feeders are hollow pipes that allow chlorine and bromine tablets or sticks to slowly disperse in the water. Chemicals are fed into the pipe that is submerged into the water. The water slowly disperses the chemicals. This eliminates the exposure to harmful gases and particulates that the chemicals create. These swimming pool hard water treatment usually work in conjunction with a pool's vacuum and filtration system. One great advantage of these swimming pool hard water treatments is that they are very affordable. An erosion feeder costs only $60.

Chemical controllers

These water treatments for swimming pools work like a chlorinator and a testing kit. Chemical controllers control the input of all pool-cleaning chemicals, and they automatically feed the needed chemical treatments into the pool whenever the water needs them. They usually come with sensors that regularly test the water's chemical composition. Chemical controllers can support swimming pool hard water treatment such as hydrochloric acid, chlorine, bromine, and metal ions. However, they are one of the most expensive swimming pool hard water treatment available. A chemical controller costs $2,500.
