shock = bleach = chlorine = liquid shock they are all the same thing, sodium hypochlorite. only diffrence is concentration levels, as long as the "straight regular old bleach" has no scents or additives its fine to use. you are bringing up your chlorine levels in the pool to 15 Parts Per Million. hope that clears some stuff up for you.
