Great product
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.

Pool store prices are ridiculous
Same chemicals that you could buy at a pool store but nowhere near the price they charge. I started using a product called PoolRx, look it up on Amazon, it cut my chemical usage by more than half last year, only buy chlorine and get my water tested at pool store then either get what I need from Walmart or Amazon

It’s ok
