How To Use


Feeder or Floaters: Add 16 ounces (approximately 23 tablets) per 10,000 gallons of pool water to feeder or floater. Adjust the feeder or floater following manufacturer’s instructions to establish a free available chlorine level between 1–4 ppm. Allow water to circulate at least 4 hours and then test for the free available chlorine level.


Add 16 ounces (approximately 23 tablets) per 10,000 gallons of pool water per week, or as often as needed, to the floater or feeder to maintain a constant free available chlorine level of 1-4 ppm. Sunlight, rainfall, temperature, number of swimmers, and frequency of pool use affect the rate of chlorine residual loss so check the floater or feeder often and refill as needed
