Water softener salt needs to be chemically pure. Most rock salt has high levels of impurity because it is untreated. Rock salt is therefore not normally suitable for water softeners.
Sea salt (or solar salt) will start off impure. Sophisticated processors can then wash it repeatedly to achieve the purity required for water softeners. However you should be wary of using poorly washed sea salt as high levels of hardness minerals (and even sand) can require frequent cleaning of salt tanks. Julian Hobday of KindWater
