Summer is almost here and it's time to get your pool ready for family and friends. Pool water is a delicate balance of chemicals, and if calcium hardness levels are too low the "soft water" will corrode pool equipment. Ensure your pool's calcium levels are perfectly balanced and your pools pH levels are kept between the recommended 7.4 to 7.6 with our Calcium hardness increaser. Having balanced pool water helps keep your pool clean and clear, and allows your sanitizer to work better, so you can enjoy your pool safely all summer long.
