Answer:

If your pool smells of chlorine, it is likely that you are smelling the combined form of chlorine called chloramines. That odor indicates the need to shock your pool in order to eliminate the combined chlorine. Adding more free chlorine or non-chlorine shock is the way to do this. Free available (good) chlorine smells fresh and even when high does not smell like sweaty socks or a gym locker room. Smell some fresh bleach with a very high chlorine level to be convinced.
