Our chlorine tablets are manufactured with a stabiliser to help prevent the destabilisation and destruction of the chlorine by sunlight and UV rays. This prolongs their usefulness as a sanitiser over other types of non-stabilised chlorine and makes them ideal for use in swimming pools, spas and hot tubs whether located indoors or outdoors.
Tablets are an alternative to granules since they can be left in a floating dispenser or skimmer to release chlorine for a continous period of time to maintain a desired chlorine level. Note: remove the dispenser from the water whilst the pool is in use. Trichloro-1,3,5-triazinetrione > 99%
