Chlorine is a disinfectant used to kill bacteria and other organisms in the water. There are three types of chlorine for pools, and each type has its benefits and drawbacks: liquid chlorine, calcium hypochlorite, and sodium hypochlorite.
Liquid chlorine is a concentrated form of chlorine that is usually stored in a drum or tank. It is usually diluted with water before it is added to the pool. Liquid chlorine is effective at killing bacteria and other organisms, but it can also be corrosive to metal equipment and surfaces.
Calcium hypochlorite is a dry form of chlorine that is often used to chlorinate pools. It comes in the form of a tablet or powder and releases chlorine when it dissolves in water. Calcium hypochlorite is less corrosive than liquid chlorine, but it can still cause damage to metal equipment and surfaces over time.
