Polyclear™ Maxipolish is a non-chlorine sanitizer, water soluble, organic cationic polymer that is very stable in pool water. It is not affected by sunlight, temperature, or mild changes in pH. This polymer possesses powerful flocculating and clarifying properties that allows it to be dosed every two weeks after an initial dose has been added to the water. Further doses depend mainly on the bathing load and airborne infections during rain and wind storms. Add two (1) half gallon of PolyClear™ Maxipolish per 10,000 gallons every two weeks during the pool season.
