计算需要向泳池添加多少氯气。输入当前和目标游离氯水平，获取液体、颗粒或片剂氯的精确剂量。
Enter your current and target free chlorine levels to calculate the required dose. The ideal free chlorine range is 1-3 ppm (or 2-4 ppm if your CYA is 30-50 ppm).
Liquid chlorine (sodium hypochlorite 10-12%) acts fast but has a short shelf life. Granular chlorine provides more precise dosing and longer storage.
Chlorine degrades quickly in direct sunlight and high temperatures. Using CYA stabilizer (30-50 ppm) can significantly reduce chlorine consumption.
家用游泳池的理想游离氯（FC）水平为1-3 ppm。如果使用CYA稳定剂（30-50 ppm），请维持2-4 ppm。
氯气在直射阳光（紫外线）下会迅速分解。没有CYA稳定剂，阳光可能在几小时内耗尽泳池中的氯气。维持30-50 ppm CYA可将氯气消耗减少多达50%。
