Our Bromine tablets, 1 in diameter, work best at 2.0 to 4.0 ppm. Its germ and algae killing is much less dependent on pH than is chlorine and there is no stabilizer build-up. Do not dispense in the skimmer. Remember that bromine dissolves only 1/10 as fast as chlorine and as a result requires more surface area exposure. We recommend the use of a brominator. Its germ and algae killing is much less dependent on pH than is chlorine and there is no stabilizer build-up. Please keep in mind that spent bromine is still useful in killing bacteria. Keep pH between 7.2 and 7.6 and never allow to fall below 7.0. The dosage necessary for your pool will change considerably depending upon those factors that burden the disinfection system. Establish an effective active bromine residual of between 2 and 3 ppm. Test water frequently using a reliable test kit. Adjust the flow rate through the brominator if necessary to maintain the active bromine residual. Dosage: Add 17 tablets per 10,000 gallons every 5-7 days or as needed to maintain a bromine residual of 2-3 ppm at all times. Feedthrough spa float or automatic brominator.
