Calcium is a naturally occurring mineral that is frequently found in high concentrations. It’s important to control its levels to ensure proper water quality and maintain the beauty of your pool. High pool water calcium hardness levels, especially above 400 PPM, can sometimes reduce the clarity of water and cause scaling issues.
