Specifications Brand: Poolife Part Number: 42122 Installation & Operation Tips Deploy tablets in a floating dispenser, automatic chlorinator, or skimmer basket for proper distribution. Never load tablets into dispensers or feeders that have previously held different chemical products. Avoid placing tablets directly into the pool or allowing them to rest against plastic or metal surfaces. Keep water chemistry balanced: pH 7.2 - 7.6, alkalinity 80 - 120 ppm, calcium hardness 200 - 300 ppm. At season opening: balance water chemistry, apply shock treatment, and stabilize before beginning regular chlorination. For routine chlorination: place one tablet per 10,000 gallons into a skimmer basket or floating dispenser. Operate the filtration system for a minimum of 8 hours per day to safeguard your liner. Do not allow swimmers to enter the pool when chlorine readings exceed 4 ppm. SEO Tags poolife poolife mpt extra chlorinating tablets 42122 poolife extra chlorinating tablets 42122
