This Clorox Pool&Spa pH Up worked well for balancing my pool water when the pH dropped too low. I noticed my water was starting to feel a little harsh and irritating, and after adding this, things evened out within a short time. The granules dissolved easily and didn’t leave any cloudiness behind, which I appreciated. It was also simple to measure and apply, so I didn’t feel like I was guessing during the process. After using it, the water felt noticeably more comfortable—less sting in the eyes and overall a smoother swimming experience. It also helped stabilize the rest of my chemical levels once the pH was back in range. Overall, this is a reliable, straightforward product that does exactly what it claims and helps keep pool water balanced and comfortable.
