Clorox Pool&Spa pH Up Pool pH Increaser, 4 lbs

Clorox pH Up raises low pH in your pool that can cause red, irritated eyes and expensive damage to your pool equipment. Use these as needed to achieve a suitable range of 7.2 to 7.6 to keep your water swim-ready and clear. Pool supplies are for use in traditional chlorine and salt chlorine pools. Test and balance your pool weekly to maintain clear water, longer-lasting equipment and comfortable swimming. It will help keep pools ready for children and adults to have fun and exercise safely. Swimming pool pH increaser helps maintain a proper pH of 7.2 to 7.6. 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 the pH is too low, corrosion can occur, and the pool water will irritate your skin.
