AquaSPArkle Spa Bromine Tablets should be dosed via a floating dispenser. When set up correctly your floating dispenser will dispense the correct amount of bromine into the spa to maintain the ideal level between 3.0 to 5.0mg/l and all you need to do is top up 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 Bromine Tablets are designed to maintain bromine levels (as they are slow dissolving), so before using them the correct bromine level should be established using Spa Bromine Granules. Bromine sanitising tablets are becoming more popular with spa and hot tub owners. They are a little more expensive than Chlorine but Bromine is less likely to cause eye, skin or nasal irritation and is widely respected for its efficiency over a wider pH band. Instructions - These tablets are designed for use with bromine feeders and floating dispensers. - When feeder device requires refilling with tablets always follow manufacturers instructions. - Ensure tablets used in the feeder are of the same chemical (Bromo-Chloro- Dimethyl Hydantoin). If other materials have been used previously, wash out feeder thoroughly before adding tablets. - Adjust feeder to ensure a constant bromine residual is present in the spa. - Check bromine levels regularly with a Test Kit and maintain a bromine residual of 3 5 mg/l (ppm) for domestic spas and 4 6 mg/l (ppm) for commercial spas. *Freshly filled new spas or spas left drained for a period of time require an initial start up dose of 20mg/l (ppm) of free chlorine circulated for a minimum of 212 hours. - Check pH value regularly with a Test Kit and maintain levels between 7.2 - 7.6. General Precautions Dosing - Wear eye and face protection and ensure granules are not blown back into your face. - Never mix with other chemicals including household cleaners as a dangerous reaction may occur. - When pre-dissolving always add product to water and not vice versa. Handling/Storage - Handle products in a well ventilated area - preferably outdoors. - Wash hands after use. - Ensure chemicals do not become damp in storage - store in a cool dry place.
