• Increases calcium hardness levels
• Pure flakes minimize clouding in pool water
• Prevents long term damage to vital pool components
• Easy to use application
• Water Hardness levels in water should be maintained between 180-400 ppm
• If calcium levels are low, add 1.25 pounds per 10,000 gallons of water to increase hardness levels 10 ppm
• Avoid increasing hardness more than 30 ppm every couple hours.
