Calcium Carbonate - aka Hard Water

A chemical compound found in nature as calcite (in limestone, marble, and chalk) and aragonite (in pearls) and in plant ashes, bones, and many shells.

Carbonate Water Scaling Basics

We know that hard water contains particularly high quantities of minerals, inparticular calcium carbonate.  These minerals can dissociate from the water and settle on top of surfaces. The result is a crust-like scale, which accumulates on pipes and faucets, as well as skin and clothing. Eventually, it affects the functioning of appliances and plumbing resulting in costly repairs.

How To Prevent Scaling   

The only way to prevent calcium cabonate scaling is to remove it from the water so that it is unable to build up on surfaces. This is where a water softener comes in. A water softener contains an ion-exchange resin that is negatively charged and attracts the positively charged calcium carbonate and other minerals within hard water. Over time, the ion-exchange resin can become so clogged with particles that it becomes positively charged and can no longer attract other minerals to remove them from the water supply. Salt is added to a water softener to prevent this, however, there are some contaminants that salt alone cannot remove. Pro Res Care is a liquid water softener cleaner that helps to restore the ion-exchange resin to peak efficiency.
