1. Adjust the pH to 7.2-7.8 (ideal pH is 7.4-7.6), the Total Alkalinity to 80-120 ppm depending on type of primary sanitizer used (80-100 ppm for sodium hypochlorite, calcium hypochlorite or lithium hypochlorite and 100-120 ppm for dichlor, trichlor or bromine tablets) and Calcium Hardness to 200 ppm minimum.
2. Superchlorinate with Leslie’s Swimming Pool Supplies Power Powder Plus, Power Powder Pro or Chlor Brite to attain a Free Available Chlorine (FAC) level of 1—4 ppm. Follow use directions on those product labels.

ROUTINE USE: The amount of Leslie’s Swimming Pool Supplies 3″ Jumbo Tabs that must be added on a routine basis will vary with individual pool conditions such as bather load, water temperature, organic contaminants and other conditions. Normally, one tablet per 10,000 gallons of pool water will be needed every week. Maintain a Free Available Chlorine (FAC) level of 1—4 ppm at all times. It may be necessary to increase the chlorinator feed rate or superchlorinate during heavy periods of use to maintain this FAC level. Maintain the pH between 7.2—7.8 (ideal pH is 7.4—7.6), the Total Alkalinity between 80—120 ppm depending on type of primary sanitizer used (80—100 ppm for sodium hypochlorite, calcium hypochlorite or lithium hypochlorite and 100—120 ppm for dichlor, trichlor or bromine tablets) and Calcium Hardness between 200—400 ppm. Test regularly with a reliable test kit and make the necessary adjustments using the appropriate Leslie’s pool care product. To remove excessive organic materials and keep the water sparkling clear, superchlorinate weekly with your preferred Leslie’s shock product when water temperatures are above 80°F. Follow use directions on those product labels. You may only need to superchlorinate every other week when water temperatures are below 80°F. Reentry into treated swimming pools is prohibited above levels of 4 ppm of chlorine due to risk of body injury.
ALGAE CONTROL: In case of algae, superchlorinate with Leslie’s Swimming Pool Supplies Power Powder Plus according to the use directions on that product label. Pool should not be entered until the chlorine level is 1-4 ppm.
