  • Did the job for less.
Size: 1 Count (Pack of 1)
I bought this item to save a little money as opposed to buying a similar product from our local pool supplier. Its purpose is to lower the ph level in our above ground pool. My wife has sensitive skin and felt fine in the treated water. Mission accomplished, money saved. Highly recommended.

  • Reliable and Effective pH Control for Crystal Clear Pool Water
Size: 1 Count (Pack of 1)
Maintaining the perfect pH balance in my pool has always been a priority, and the Clorox Pool&Spa™ pH Down has become an indispensable part of my pool care routine. Quick and Efficient pH Reduction: This product works swiftly to lower high pH levels, bringing the water back to the ideal range of 7.2 to 7.8 ppm. I’ve noticed that after application, the pH levels stabilize within a few hours, ensuring the water remains comfortable for swimmers and safe for pool equipment. User-Friendly Application: The granulated formula dissolves quickly without clouding the water, making it easy to apply. The packaging provides clear instructions, and the resealable bag ensures safe and convenient storage. Enhanced Safety Compared to Alternatives: Unlike liquid acids, this dry acid is safer to handle, reducing the risk of spills and fumes. It’s a more manageable option, especially for residential pool owners seeking effective results without the hazards associated with harsher chemicals. Additional Benefits: Regular use of this product not only maintains optimal pH levels but also helps prevent scale formation on pool surfaces and equipment. This proactive approach extends the lifespan of pool components and ensures a more enjoyable swimming experience. Final Thoughts: The Clorox Pool&Spa pH Down is a reliable and effective solution for maintaining balanced pool water. Its ease of use, safety, and efficiency make it a top choice for both novice and experienced pool owners. I highly recommend it to anyone looking to keep their pool water crystal clear and perfectly balanced ... show more
