计算需要添加多少泳池冲击剂（次氯酸钙或二氯）来超氯化您的泳池。分解氯胺并有效消毒。
Enter your pool volume to calculate the required shock dose to super-chlorinate your pool to 10 ppm free chlorine. Shock treatment breaks chloramines and kills resistant algae.
Always shock in the evening or at night. Daytime sunlight rapidly degrades unprotected chlorine (shock does not contain CYA stabilizer).
Wait until free chlorine drops back to 1-4 ppm before allowing swimmers to enter (typically 8-24 hours). Pre-dissolve shock in a bucket of water before adding.
泳池冲击处理（超氯化）涉及将游离氯水平提高到10 ppm或更高，以分解氯胺、杀死藻类并消除细菌和其他污染物。当泳池有强烈氯气味、大量使用后、暴风雨后或出现藻类时需要进行。
等到游离氯降回1-4 ppm后再允许游泳者入水。这通常需要8-24小时。游泳前务必进行测试。
