Floating pool chlorinators offer a simple way to add chlorine to your swimming pool. They also can add a bit of whimsy: Manufacturers produce the floating chlorinators in a number of designs ranging from yellow ducks to alligator heads. Despite what the chlorinator looks like, they all serve the same purpose as a housing for the chlorine tablets while they dissolve into the water. Using them is simple and within the capabilities of most pool owners.
Open the floating pool chlorinator, and place into the housing one chlorine tablet for every 10,000 gallons of pool size. Close the container, and place the floating pool chlorinator back into the pool. Follow all manufacturer's instructions concerning the handling of the chlorine tablets and the number of tablets to use for the size of your pool.
Monitor the chlorine level of the pool after one week and every week thereafter. Use a chlorine test kit, and follow manufacturer's instructions. The goal is between 2 and 4 parts per million of free chlorine. Add or reduce the number of chlorine tablets in the floating pool chlorinator to increase or reduce the amount of chlorine in the pool.
Monitor the levels of alkalinity every week as well. The same test kits measure the alkalinity, with the desired range for the pH at about 7.5 and the total alkalinity at between 80 and 130 parts per million. Adjust the number of chlorine tablets in the floating pool chlorinator to change the alkalinity.
