Haviland c002729-cs20b6 Spa Hardness Increaser 16 Oz

Product Description

The HAVILAND c002729-cs20b6 is a calcium hardness increaser formulated for spa and hot tub water balance. Available in a 16 oz container, this white flake formula dissolves readily in water without clouding the spa. Low calcium hardness causes water to become aggressive and corrosive, attacking equipment surfaces, fittings, and shell materials over time. Adding this increaser brings hardness levels up safely and helps protect spa components. Pool and spa service technicians rely on this type of balancer as a standard part of a complete water chemistry program.

This product is used in residential and light-commercial spas and hot tubs where calcium hardness levels have tested below the recommended range. Proper hardness balance reduces corrosion on heater elements, pumps, and plumbing components. It is applied directly to spa water as part of a routine chemical balancing process. The flake form allows for controlled dosing during water startup or ongoing maintenance cycles.
