Description
Keep your water comfortable and balanced with Master Clear® pH Up. When pH drops too low, water can turn corrosive, irritate skin and eyes, and wear on your spa's equipment and surfaces. pH Up raises pH and alkalinity to restore balanced water chemistry, protecting your MasterSpas hot tub or swim spa and helping your sanitizer work as it should.
