Granular chlorine is the world's most common spa water sanitiser. It's easy to use and extremely effective at eliminating bacteria.

These chlorine granules are very fine and dissolve almost instantly in warm water so that the chlorine is available immediately, making them ideal for heavily-used spas, where you don't have time to wait for tablets to erode. HTH chlorine is specifically formulated for use in spas. It smells nicer than most brands of pool chlorine and it is more stable at high water temperatures.
