Pool bromine is a chemical compound used to disinfect and sanitise swimming pools and hot tubs. It is an alternative to chlorine and is often preferred due to its less harsh smell and ability to remain effective at higher pH levels. Bromine tablets or granules are added to the water, where they dissolve and release the active ingredient. This helps to kill bacteria and other harmful organisms, keeping the water safe and clean for swimmers. Pool bromine is an excellent choice for those looking for a reliable and effective way to maintain their pool or hot tub.
