Adjust the chlorine dispensing rate of the floater or in-line feeder to provide 2.0-4.0 ppm of free chlorine residual as determined by a reliable test kit. The initial startup and weekly maintenance dosage is 1 to 3 tablets per 10,000 gallons although this dosage may vary due to unusual conditions such as heavy bather loads, wind, heavy rains, and high temperatures; therefore, frequent use of a reliable test kit is recommended. Use the test kit as a guide to maintain the pH at 7.4-7.6 and total alkalinity at 80-130 pom. Pool chlorinating tablets are intended for use in a floater or in-line feeder only. Do not add these tablets directly to the pool or mix with any other chemicals. Reentry into treated swimming pools is prohibited above levels of 3 ppm of chlorine.
