Haviland DuraChlor Alkalinity Increaser 10 lb Pail (C002669-CS74C1)

The Haviland DuraChlor Alkalinity Increaser (C002669-CS74C1) is a fast-dissolving, 100% Sodium Hydrogen Carbonate formula designed to quickly raise and stabilize total alkalinity in swimming pool water. This 10 lb pail offers great value for pool owners who want to maintain proper alkalinity (80–120 ppm) — the essential buffer that prevents erratic pH swings and protects your equipment, surfaces, and swimmers all season long.

🚩 PRO TIP

Add this product with the pump running, broadcasting it across the deep end. Wait at least two hours before retesting. If alkalinity is very low, dose in stages (no more than 10 ppm per treatment) to avoid overshooting your target range.
