The most widely used and effective agents are those that contain chlorine or bromine. Chlorine is available in different types for different purposes: calcium chloride, day chlorine, calcium chlorine, shock chlorine or weekly chlorine (multi chlorine).
Calcium hypochlorite daily chlorination
Daily chlorination is the most effective way to disinfect pool water. Calcium hypochlorite in small tablets dissolve slowly and releases chlorine into the pool water.
Dosage: For seasonal start up, maintenance dosing or shock chlorination, see instructions on the package.
Handling: Place the tablets in the filter basket of the skimmer or in a chlorine dispenser. Always read the label and product informa-tion on the package.
