Product Details
✓Why Decrease Hot Tub pH? Did you know that the water in your spa should be maintained at a pH of 7.2 to 7.8 and total alkalinity from 80 to 140 ppm? Using a pH down for hot tub or spa pH decreaser will help you maintain your hot tub chemistry.
✓pH Down For Hot Tub Spas - AquaDoc's spa pH reducer helps you maintain the balance of your hot tub's chemistry. If your spa's pH measure is outside its range, it is important to use a pH decreaser to help reduce cloudy water, scale build-up, and more.
