Your cart is empty.Clorox Pool&Spa pH Down lowers high pH that can cause itchy, irritated skin and scale formation on your pool surfaces. The granulated formula simple to apply and dissolves fast, and the easy pour application bag makes this a simpler, faster solution compared to Muriatic Acid. High pH can cause dry, itchy skin and hard-to-remove scale on pool surfaces. Use this pH decreaser as needed to achieve a suitable range of 7. 2 to 7. 6 to keep your water swim-ready and clear. For use in both traditional chlorine and salt chlorine pools. Test and balance your pool weekly with the Clorox Pool app to maintain clear water, longer lasting equipment, and comfortable swimming. Maintaining proper pH of 7. 2 to 7. 6 is both important and easy. Important, because if pH is too high, chlorine cannot effectively sanitize and disinfect your water and water will irritate your skin and eyes when you swim. If pH is too low, corrosion can occur and the pool water will irritate your skin.

I was kinda tired of using Muriatic Acid and having to be so careful and the fumes. I tried this and it works great. I use the recommended amount on the bag and it gets my pH right within about 45-60min. I love it

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.

Product works well lowering the PH in my pool and the price on Amazon is really good. Normally purchase at Walmart but save $2 a bag going Amazon.

Clorox is a well known brand and I’ve always had great luck with using their products. This cleaned up my pool issue of Green water and returned it to its clear state. Definitely will buy again to maintain the proper pH in my water. Very good price for the amount that you get dissolves very well.

Nothing wrong with the product, we bought it since it has the same active ingredient as the old discontinued Sani Flush. It didn't work.I did test it's ability to lower pH and it tested perfectly, as advertised.I can't give it a substandard review because I bought it for off-label use.
