Tests for 3 important chemistries in seconds: Potassium Monopersulfate, pH, and Total Alkalinity.

Monopersulfate (MPS) is an oxidizing agent used in mineral purification systems such as Frog®, SpaFrog®, Nature2®, Pool, or Spa. Monopersulfate can also be used as an oxidizer for brominated pools and spas.

To keep you spa water clean and healthy, test the water before and after each use! If used in a pool we recommend testing at two ends or sides of the pool a minimum of twice a week. Its also a good idea to write down your results each time you test.
