With HTH chlorine tablets of 7 grams, you can efficiently disinfect the water in your pool, spa, or hot tub. The chlorine tablets do not contain cyanuric acid, eliminating the risk of over-stabilization.

These chlorine tablets are designed to dissolve slowly when they come into contact with the swimming water, resulting in a continuous and stable release of chlorine. The chlorine is unstabilized, which means it works very quickly and effectively but also depletes faster. Because these are small tablets in a 2.5 kg package, it is an ideal choice for above-ground pools!
