LaMotte 6846A-J Calcium Hardness Tablets – Water Hardness Reagent (100-Count Blister Pack)

The LaMotte 6846A-J Calcium Hardness Tablets are used to measure calcium hardness levels in pool, spa, and drinking water systems. These tablets are blister-packed for easy dispensing, clean handling, and long-term shelf stability. Designed for use with LaMotte tablet-style test kits, including Octa-Slide® and Pool Mgr® kits, the tablets dissolve in sample water to indicate hardness through a titration color-change method.
