I’ve been using Clorox Pool&Spa pH Up for several seasons now, and it has consistently delivered excellent results. Maintaining the correct pH balance in my pool is crucial for both swimmer comfort and equipment longevity, and this product makes it straightforward. Fast-Acting and Easy to Use: The granulated formula dissolves quickly, allowing for rapid adjustments to the pool’s pH levels. The easy-pour application bag simplifies the process, making it convenient even for those new to pool maintenance. Improves Swimmer Comfort: Since incorporating this product into my pool care routine, I’ve noticed a significant reduction in eye and skin irritation among swimmers. Maintaining a pH level between 7.2 and 7.6 has never been easier. Protects Pool Equipment: Balanced pH levels are essential to prevent corrosion of pool equipment. Using Clorox pH Up has helped in preserving the integrity of my pool’s components, saving me from costly repairs. Trusted Brand: Clorox is a name I trust, and their pool products uphold the quality and reliability I expect. This pH increaser is no exception. Final Thoughts: If you’re looking for an effective solution to maintain optimal pH levels in your pool, Clorox Pool&Spa pH Up is an excellent choice. It’s user-friendly, efficient, and backed by a reputable brand.

Instead of traipsing to our close to home Leslie's pool store for fast convenience, I'm happy to have bought this on Amazon. Works like a charm & much cheaper! I don't usually handle pool chems (husband does), but this is easy peasy.

It’s sodium carbonate, baking soda, why pay more than the minimum for the same thing with a fancy label? Makes no sense. This is 100%, nicely granulated, flows well, no caking noticed. For convenience I refill the original plastic container that came with the spa starter kit. FWIW, I’ve found all the Clorox spa products to be most cost effective compared to the competition, so far.

Does the job well, just wish it came in bigger bags. Had to use multiple bags to bring up the Ph, but I have a bigger pool. Bags are easy to open, mixes well with the water.
