    Corrosive water comes from calcium hardness levels dropping under ideal range in a pool. Low calcium hardness damages pool equipment, so it is imperative to use calcium hardness increaser to bring up the pool's calcium hardness levels. Calcium hardness is a measure of all the dissolved calcium present in your pool's water. When the calcium hardness level of your pool drops below the ideal range, you will end up with corrosive water. As low calcium hardness can damage your pool and pool equipment by causing corrosion, staining and etching, you will need to use calcium hardness increaser to bring your pool's calcium hardness level back up.
    Our swimming pool calcium hardness increaser will quickly correct pool chemical levels, restoring your pool's water chemistry and protecting your pool and equipment. Containing calcium chloride and available in granular form, our calcium hardness increaser is convenient to use and will work quickly to increase calcium hardness in your swimming pool so you can rest easy knowing that your pool equipment is protected.
