    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. Read more

    I recently started using Clorox® Pool&Spa™ Swimming Pool products, and they’ve made pool maintenance so much easier! The chemicals are highly effective in keeping the water crystal clear and free from algae. I especially love how simple the instructions are, and the results are noticeable after just a short time. Whether it's shock treatments or balancing the water chemistry, everything works perfectly to maintain a clean and safe pool. If you want hassle-free pool care with great results, I highly recommend this line of products! Read more

    This stuff is a strong granulated acid. It's also a good clarifier when it's offset with baking soda. It may contribute to bleaching the pool liner. I previously used Clear Balance but the price went up too much. Read more

    This is my go-to product when PH rises in my pool. Directions are clearly written on the package for how much to use, and I have found that going by those directions works quickly to get my pool water's PH back in the normal range. Read more

    We have a vinyl 6,000 gallon above ground pool. I prefer muriatic acid to this stuff. It dissolves faster and seems safer to work with, when the right precautions are used. However, this powder works and I would absolutely get it again. The acid is only sold at one store locally and this stuff is seasonally available at walmart and the like. Read more
