This unique technology provides you with bromine in a granular form, which makes application easy as it can be dosed directly into the spa water without having to pre-dissolve or apply via a chemical feeder. Bromine is an effective sanitiser, which is not as pH sensitive as chlorine, and its reduced odour creates a pleasant bathing environment. Maintain bromine levels of 4-6mg/l at all times with regular shocking using Spa Lite to ensure effective sanitisation of your spa.
