Calcium Booster by Leisure Time is a liquid formula that is will raise the calcium level in your hot tub. Maintaining proper calcium hardness levels will prevent equipment damage caused by corrosion and helps reduce foaming.
Water containing low calcium will etch plaster (commonly found in in-ground hot tubs) and corrode equipment and may cause foaming. By maintaining a hardness level of 150 to 400 ppm, the spa's life will be extended. Calcium levels can be measured with most test strips or test kits. Calcium Booster is compatible with all sanitizers including bromine, chlorine, mineral sticks and biguanide.
Directions for use:
Adding one ounce of Calcium Booster will raise the calcium level in your hot tub by 7 ppm in 500 gallons of water. Simply test for your calcium level and if low, add the Calcium Booster directly into the hot tub water for quick results.
