Potassium Monopersulfate is also labeled as Non-Chlorine Shock and is sometimes called oxone (ox - own). It is a chemical patented by Dupont and is used primarily as an oxidizer. It is fast acting to rid Combined Chlorine in a pool or spa. It will increase/enhance the oxidizing ability of the chlorine in the water, but then reduce it back down to a safe level, usually within 15 - 30 minutes, so the kids can swim again the same day, rather than waiting for tomorrow.

Hope this has been helpful
