Haviland DuraChlor Alkalinity Increaser 25 lb Pail (C002669-PL25)

The DuraChlor Alkalinity Increaser 25 lb Pail (C002669-PL25) by Haviland is a professional-grade pool balancing chemical formulated with 100% Sodium Hydrogen Carbonate (Sodium Bicarbonate). Designed to quickly raise total alkalinity in swimming pool water, this fast-dissolving granular powder helps stabilize pH levels, preventing the damaging "pH bounce" that can corrode equipment and irritate swimmers. Compatible with all pool types and systems, it is an essential part of any regular pool maintenance routine.

🚩 PRO TIP

Always balance your total alkalinity before adjusting pH. Stabilizing alkalinity (target: 80–120 ppm) will often bring pH levels naturally closer to the ideal range of 7.4–7.6, reducing the need for additional pH adjusters and saving you money on chemicals.
