AquaDoc Spa pH Decreaser for Hot Tub - 32oz (2-Pack) - Sodium Bisulfate Spa pH Down for Water Balance - Made in USA

2-pack pH Decreaser - Helps Lower High pH Levels. When spa water becomes too basic, it can lead to cloudy water, scale formation, and reduced sanitizer performance. This Hot Tub pH decreaser helps bring pH levels back into the proper range for more comfortable soaking. Supports Balanced Water Chemistry - Formulated with sodium bisulfate, it helps return pH toward the recommended 7.2 to 7.8 range, supporting clearer water and more consistent sanitizer effectiveness. Helps Improve Sanitizer Performance - High pH can limit how well chlorine or bromine works. Correcting pH as needed helps sanitizers maintain effectiveness in properly balanced water without directly changing sanitizer levels. Easy-Pour Liquid Formula - The liquid formula mixes smoothly into circulating spa water for consistent results. Test your water, add the directed amount, and allow circulation before retesting. Made In The USA - At AquaDoc, we make high-quality hot tub chemicals designed to support balanced, comfortable water. Proudly made in the USA with consistent quality standards. Maintain clear, comfortable, and well-balanced spa water with AquaDoc Spa Down for Hot Tub. When pH levels rise too high, water can become cloudy, scale may form, and sanitizer performance can decline. This sodium bisulfate liquid formula helps bring pH back into the recommended range, supporting clearer water and a more enjoyable soaking experience. High pH may also contribute to mineral buildup and surface film over time. Adjusting pH as part of regular maintenance helps support stable water chemistry and protects spa components such as heaters, jets, and filtration systems. 1. Can it be used in hot tubs? Yes. It is designed specifically for hot tubs and spas to help lower elevated pH levels. It can also be used in saltwater spa systems when added according to directions. 2. How often should this be used?
