Hot Spring MPS is a chlorine free spa shock (oxidizer) used to effectively reduce odor-causing ammonia and chloramines, as well as soaps and oils. The result will be fresher, clearer, odor-free water. Hot Spring MPS Oxidizer is not a disinfectant, and should be used in addition to ozone, chlorine or bromine. It is recommended that you shock your spa once a week or for every hour of use, which ever is greater.
