Pool Time Calcium Hardness Increaser works to prevent pool surface damage and corrosion of pool equipment by raising calcium hardness. When total hardness levels are too low due to low calcium levels， pool equipment and surface are prone to corrosion and etching. Broadcast calcium hardness increaser to the deepest end of the pool to help maintain ideal total hardness levels of 175 to 225 parts per million.
