Calcium hardness levels | Swimart

8/1/2013· The recommended level of hardness is between 200-400 ppm; if this level is either too high or too low, there can be hard to fix consequences for your pool and its equipment. High levels may result from pool water evaporating and increasing the concentration of calcium in the remaining water as it leaves the mineral behind.
