计算需要向泳池添加多少pH增加剂或pH降低剂。获取盐酸或碳酸钠的精确剂量以平衡泳池pH值。
Enter your current and target pH to calculate the dose needed. The ideal pool pH range is 7.2-7.6. Low pH causes eye and skin irritation and metal corrosion. High pH reduces chlorine effectiveness.
To raise pH: use sodium carbonate (soda ash / pH Up). To lower pH: use muriatic acid (hydrochloric acid) or sodium bisulfate (dry acid).
Add pH chemicals in small increments and retest after 6-8 hours. Never add acid directly to the skimmer or near the pool return jets.
理想的泳池pH范围为7.2-7.6。低pH（低于7.2）会导致眼睛和皮肤刺激并腐蚀设备。高pH（高于7.8）会降低氯气效果并导致水垢。
pH对氯气效果有显著影响。在pH 7.0时，约73%的氯气处于活性形式。在pH 7.5时，只有49%处于活性状态。在pH 8.0时，只有21%处于活性状态。
