Monopersulfate is an oxidizing agent used in mineral purification systems such as Frog®, SpaFrog®, Nature2®, PoolRx™, or SpaRx™.* To test, just dip your AquaChek Monopersulfate strip into your pool or water for a quick second, and remove it immediately. You'll get results in just seconds.

To keep your pool at its best, test at each end a minimum of twice a week, and test your spa before each use. It's also a good idea to write down your results each time you test.

Comes with complete instructions in 15 languages: English, French, Spanish, Italian, Czech, Danish, Dutch, German, Greek, Hungarian, Polish, Portuguese, Russian, Swedish and Turkish.
