If the water has a strong scent of chlorine, it requires shocking chemicals.
Purchase a pool test kit that has the ability to read total as well as free chlorine.
Whenever these two chlorine reading numbers are not the same, the pool needs to be shocked.
Amount and type of shock also should be determined by the type of pool system you are using.
Shockers are available as nonchlorinated for nonchlorinated pools and chlorinated for chlorinated pools.
