Hard water is water that has a high mineral content and this usually consists of calcium, magnesium ions, and possibly other dissolved compounds.  In addition, hard water leaves deposits within an evaporative cooler's tank and water lines over time, and can form corrosion on moving parts. 

To prevent hard water damage, use Port-A-Cool's MK-47-CS Mineral Knockout with your evaporative cooler to treat hard water conditions that may damage or shorten the life of the internal components.  Protect your investment by regularly adding the MK-47-CS water treatment solution to the reservoir of your Port-A-Cool unit and see how much difference a little preventative care can make!

Note: This item contains a package of six bottles of Mineral Knockout.
