About This Item
HTH® pH Down 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 above 7.8, add HTH® pH Down directly to the pool water to decrease the pH, prevent corrosion of pool surfaces and prevent skin and eye irritation. HTH® pH Down is great for all pool types including vinyl-lined pools and salt water systems.
