  • Easy to Use and Effective in a Spa.
Size: 1 Count (Pack of 1)
Clorox is a brand that can be trusted for spa and pool chemicals-but finding the right chemicals for a spa can be challenging. After using for 3 months in the middle of winter-Clorox® Poo & Spa™ Swimming Pool pH Up works great in our 375-gallon spa-BUT, you have to derive your dosage based on your spa size-so some math is involved. For 375-gallon spa, 2 ounces is the dose I arrived at to move the pH up from 6.5 to 7.0 +/-. That is nearly equivalent to 2 heaping tablespoons. Your dosage may be different. Purchased in this packaging is a great value to spa owners and will save you significant money over purchasing from your local spa dealer. Throw some cheap plastic measuring spoons in the bag and you'll be ready to go when you need to increase your pH. Happy soaking! ... show more

  • Good quality product
Size: 1 Count (Pack of 1)
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.
