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

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.

I’ve been using Clorox Pool&Spa pH Down for a couple of seasons now, and it never disappoints. Whenever my pool’s pH creeps too high, just a small amount of this brings it right back into the ideal range. It works quickly and helps prevent cloudy water, scale buildup, and skin irritation. The instructions are clear and easy to follow, even for pool owners who are still learning the ropes. I love that it’s compatible with all types of pools, and the container is easy to store and pour from without making a mess. A must-have for keeping your pool water balanced and crystal clear. Highly recommend!

The current price is affordable comparable at this price to Liquid acid. My Ph was at or even above 8 and my TA was 140 too. I know even if I bring down the PH I need to get the TA down too (be sure your CYA is no more than 60 ppm or you need to bring it down because it interferes with the testing on TA (higher than it really is per Taylor Technologies), so remove some water and refill if you have to. This is why I use Liquid Chlorine instead of tabs because even if you started the pool with 30-50 CYA as recommened, each tab will add 6ppm CYA too and that adds up quickly causing you to go through higher amounts of Chlorine to do the job. But PH is extremely important on how much effectiveness you get out of your FC, so first PH and then address the chlorine. I have a 10,000 gal play pool and I can't keep FC in the pool, but the first thing I am getting under control is the PH which can be done in 1-2 days with this product. 7 oz of dry acid is suppose to be equal to 1 cup liquid acid. At frst the PH was stubborn to come down the first tretment of 3 cups Chlorox PH down, but each subsequent treatment of 2 cups taking about 5 treatments in 2 half days. It went like this; started at 8 ppm with 3 cups and after was still 8ppm, next treatment started at 8, came down to 7.8 over night it went back to 8, next treatment start at 8 and dropped to 7.6, I didn't stop there because my TA will 100 and my experience tells me it won't hold so I did nothr treatment right away with 22 more cups and wallah ph is 7.2 and TA is now 80 which I'm hoping is low enough to stablize the PN from constantly rising. If not I will treat again (no lower than 7.2 and test TA again and see if 60 is the sweet spot. I have added non chlorine shock and alage 60 too to control any algae blooms and some chlorine too at night only. This has taken two and one half 5 lb bags of Chlorex PH down 93% to accomplish this. I am determined and hope Chlorox doesn't increase their price or I willhave to look at other options. I can't use and won't use muriatic acid.

I have a pool with a waterfall feature, which pushes the pH up quickly unless I treat it regularly. This pH-down powder is simple to use and easy to store, so it’s become a staple for me. I keep about 10 bags on hand and add it roughly every two weeks. Since using it consistently, my water chemistry has stayed stable and I haven’t had algae issues. The price is reasonable, too—highly convenient and cost-effective.
