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 manufacturer’s 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 21⁄2 hours.
 
Check pH value regularly with a Test Kit and maintain levels between 7.2 - 7.6.
