About This Item
HTH® pH Up helps balance the pH in your pool water for healthy swimming. Test your water weekly to make sure pH is between 7.2 and 7.8 ppm. If pH measures below 7.2, add HTH® pH Up directly to the pool water to raise the pH, prevent corrosion of pool surfaces and prevent skin and eye irritation. HTH® pH Up is great for all pool types including vinyl-lined pools and salt water systems.
