      – Use 2-3 ounces daily per 10,000 gallons to maintain proper chlorine levels.
      – Use 2 Lbs per 10,000 gallons for heavy algae until algae clears.

      How do I dispense my granular chlorine?

      – If chlorine seems to be ineffective check the stabilizer also known as cyanuric acid. The correct level for stabilizer is 30-60 ppm. If the stabilizer is too low the chlorine will be used up faster making it appear that the chlorine is not effective. If the stabilizer level is too high it will slow down the oxidizing process and render the chlorine less effective. This must be compensated for by using a higher concentration of chlorine in the pool water.

      – If you believe the chlorine is defective/ineffective, you can test it by scraping a small amount of tablet into a glass of tap water. (Do not use pool water.) Dissolve and test as usual.
