Chlorine is the best known and most widely used of all pool chemicals. The use of chlorine has been driven largely for its effectiveness at maintaining clean, sanitized pool water. Pool chlorine is also used for its economical price.

Manufacturers of chlorine water purifier systems have very effectively adapted their inventions and uses of chlorine to swimming pool use. Many chlorine water filtration systems started with the intention of cleaning municipal water supplies, but Universities and industry leaders saw wider applications; such was the case with the development of Canadian Alberta water filtration systems. All of this means systems for backyard recreational purposes have had some very reputable beginnings.

Chlorine is used in different ways in swimming pools. Some chlorine chemical solutions are used in small amounts to regularly maintain residual chlorine levels. These combat bacteria and algae on an ongoing basis. Chlorine ‘shock’ solutions are also used. Shock brings the amount of chlorine up rapidly for a short period of time to quickly kill pool born pathogens.

Chlorine solutions are sold in different forms, too. Forms of pool chlorine are

liquid chlorine
granular chlorine
chlorine tablets

However, many people are not comfortable swimming in chlorine. Efforts at chlorine reduction and chlorine free pool systems have netted many advances.

Chlorine free swimming pool systems include

ozone generators
salt water pools
alternative chemicals

Unless you do choose to go the route of chlorine free, you will need to learn how to properly test and adjust chlorine levels in your pool. Testing kits rely on reactionary test strips with sodium thiosulfate and chlorine is also reduced using this chemical as well. Digital readers are now on the market, too. There are many choices to learn about. Consulting pool professionals online and at pool supply retailers is very helpful.

All pool owners should learn about chlorine, its uses and alternatives. Despite the growing number of chlorine alternatives, chlorine remains a highly efficient and dependable pool chemical choice. It’s affordability is well within reach of pool owners, where newer chlorine free pool chemical versions may not be. Ozone generators and other mechanical chlorine reducers or eliminators may not be within the budget of new pool owners, regardless of their long-term savings. Other pool owners choose to stay with chlorine strictly for its noted track record. At any rate, chlorine and its colleagues is worth considering. Knowing something about all pool chemical options will aid in your chemical and filtration system choices.
