Potassium monopersulfate oxidizes water to remove contaminants and protect key chemical levels (chlorine, pH, alkalinity, hardness).
Simply The Best
"Simple scoop lives up to its description my pool has been crystal clear the entire summer of high up in the 90’s temp. 2 scoops of simple scoop and a bag of shock and regular chlorine tablets in the floater. Is the only chemical needed. Highly recommend and will continue to purchase."
