About this item

• PREVENTS DAMAGE TO YOUR SPA - Calcium hardness is important because it prevents equipment corrosion, etching, and staining caused by low water hardness levels. Use EcoOne total hardness increaser to keep your spa’s plumbing, heating, and filtration systems in tip-top shape!
• RAISE YOUR SPA’S CALCIUM HARDNESS - EcoOne Calcium Hardness Increaser is made of pure calcium chloride, a granular powder designed to gently raise your spa or hot tub water hardness for balanced water chemistry.
• HOW TO USE CALCIUM HARDNESS INCREASER - With pumps running and water circulating, test total hardness.
