2 lb HotSpring Freshwater MPS oxidizer
Hot Springs Freshwater MPS is a non chlorine spa shock (oxidizer) used to effectively reduce odor-causing ammonia and chloramines as well and soaps and oils. The result will be fresher, clearer, odor-free water. Hot Springs 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. Apply three tbs for every 250 gallons directly to the water.
