Kleen Pool protects thousands of residential and commercial pools around the world. Just one simple application protects pools for up to SIX months. How does Kleen Pool work? Is it safe? Kleen Pool's proprietary formula is copper-based. Copper is a natural and essential mineral that has been used to sterilize water for thousands of years--notably by the ancient Egyptians and Romans. ​ Scientists continue to study the natural antimicrobial properties of copper and its effectiveness is cited in many peer-reviewed journals. Copper shuts down algae's ability to eat, grow, and reproduce--shutting it down quickly. ​ Kleen Pool is a concentrated formula and should not be ingested directly. However, with proper dosage, an adult would have to drink over 50 gallons of pool water per day to exceed the recommended copper intake. Which we do not recommend... ​ Swimming can begin immediately after application. Join The Kleen Pool family in enjoying the best water sterilization that nature offers.
