AquaSparkle Multifunctional Chlorine Tablets should be dosed via a floating dispenser. When set up correctly your floating dispenser will dispense the correct amount of chlorine into the spa to maintain the ideal level between 3.0 to 5.0mg/l and all you need to do is top up the floating dispenser with new tablets as and when required. This makes maintaining the sanitiser level in your spa very straightforward. When using a floating dispenser remember to remove it from the spa and place it on a non-bleachable surface while people are bathing. Please note Spa Multifunctional Chlorine Tablets are designed to maintain chlorine levels (as they are slow dissolving), so before using them the correct chlorine level should be established using AquaSPArkle Spa Stabilised Chlorine Granules.
