Follow these five steps when you're ready to open your pool for the season.
When opening your pool, add Sustain® Stabilizer to achieve a level of 80 ppm.
Once the stabilizer level falls below 40 ppm, it may not effectively protect your chlorine from sunlight. Your Authorized Sustain® System Dealer will check the stabilizer level when you bring your water in for your six-week check up.
Establish a Free Available Chlorine (FAC) residual to eliminate the remaining invisible contaminants in the water. FAC is the active form of chlorine that should be maintained in the ideal range of 1-3 ppm to be assured the water is sanitized. When opening your pool, add two pounds of Sustain® Shock Treatment, according to label directions, for every 10,000 gallons of water (twice the normal dose). Operate your pool's pump for 24 hours and test for FAC. If the reading is less than 1 ppm after 24 hours, continue shocking the pool (2 lbs./10,000 gallons) until 1 ppm of FAC is established when you test the following day.
For smaller skimmers, remove the 3-inch tablet dispenser before adding the Energizer Tablets, and replace after Energizer Tablets have dissolved.
