The Flowclear™ Chemical Pool Floater with a ChemGuard™ Protective Glove helps you easily handle and maintain your pool chemical levels. Getting any kind of pool chemicals on your hands could lead to skin irritation and bleach marks. Use the lid as the ChemGuard Protective Glove to handle the chemical tablets safely while also feeling confident in the secure, dual-action child safe lock, which keeps the chemicals inside of the floater and away from little hands. Simply add the up to 7.6 cm / 3 in. chlorine or bromine tablets (not included), and set the floater in the water to evenly dispense chlorine, giving you clean, healthy pool water. Not sure how much chlorine to add? Use the adjustable dial to control the release of chemicals based on the size of your pool, and you'll get the right amount every time. The floater also includes an integrated thermometer so you can easily read the temperature gauge in both Celsius and Fahrenheit before you take the plunge! Keeping your pool clean has never been so safe and easy.
