Shocks are oxidizers that eliminate organic matter, kill algae, and eliminate chloramines. 

The presence of chloramines is one of the most common pool water problems.The chlorine odor that is associated with chloramines is often mistaken as “too much chlorine” – but is actually too little.   Shocking your pool will reduce or eliminate chloramines. If you achieve “breakpoint chlorination” when shocking, you will eliminate chloramines.
