Pool Mate 1-1407 Chlorine Tablets 3 Inch, 7-Pounds;

Pool Mate 3-Inch Chlorine Jumbo Tabs are the strongest chlorine tablets on the market today and they come individually wrapped for safer and easier handling. Each tab is stabilized to protect against harmful UV rays, thus improving the chlorine residual in your pool by guaranteeing a longer-lasting, slower dissolving release. Each tab weighs 8 ounces. Daily instructions: 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 ppm. 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. Keep product dry in a tightly closed container when not in use. Store in a cool, dry, well-ventilated area away from heat or open flames. Do not reuse or refill empty container.
