There is not a solitary measurement or rule for how much chlorine to add to a pool. What new pool owners should remember is, testing the pool’s chlorine levels determines how much they should add. Pool owners can purchase test strip kits from pool supply stores or online stores. The reason why these kits are necessary is that multiple factors can influence a pool’s chlorine levels. When chlorine mixes with body lotions, urine, or environmental elements, it causes a reaction. Using these kits to measure chlorine levels will eliminate any uncertainty when it comes time to balance these discrepancies.
