Shock (1 Lb) Non-Chlorine, Potasium MonoPersulfate

The best shock to use so you can swim in 15 minutes.  Great for Salt pools to activate the salt process and create chlorine.  Also great for spas that are using Bromine to activate the bromine.

Use 1 lb per 10,000 gallons no matter what your chlorine level is. If you have no chlorine level you must use a chlorine shock.
