There are two main reasons for the rapid consumption of residual chlorine in swimming pools. One is the excessive pollution load in the pool, leading to a high consumption of free residual chlorine in the water. The other is direct sunlight on the pool, causing the free residual chlorine in the water to evaporate.

If the rapid consumption of residual chlorine is due to the first reason, to ensure the safety and health of swimmers, we recommend adding chlorine disinfectant promptly when free residual chlorine in the pool water is detected to be below 0.5ppm.

If the rapid consumption of residual chlorine is due to the second reason, you can add Chlorine Stabilizer to achieve a cyanuric acid concentration of 30-40ppm in the pool water.

Additionally, chlorine disinfectants can be classified into two types: stabilized chlorine and unstabilized chlorine. TCCA (Trichloroisocyanuric acid) and SDIC (Sodium dichloroisocyanurate) belong to stabilized chlorine, while calcium hypochlorite and sodium hypochlorite belong to unstabilized chlorine. The use of salt chlorinators also falls under unstabilized chlorine. We recommend using TCCA 2g Instant tablet as the primary disinfectant for outdoor swimming pools.
