Chlorine stabiliser is an organic compound that protects chlorinating products from the sun. It is also known as cyanuric acid and is sometimes referred to as “conditioner.” Water that is stabilised offers pool owners a definite advantage over unstabilised pools. For instance, for every 35 minutes that a pool is exposed to the sun, the water will lose half of its HOCI (the hypochlorous acid that forms when chlorine is dissolved in water and that is responsible for the disinfecting power of chlorine.)
