Haviland DuraChlor pH Down 5 lb Granular Pool pH Reducer (C002599-CS77C2)

The DuraChlor pH Down 5 lb (C002599-CS77C2) by Haviland is a professional-grade pool water balancer formulated with 100% Sodium Bisulfate (dry acid). This fast-dissolving granular formula safely and effectively lowers pH levels in swimming pool water, correcting high pH conditions that cause scale buildup, cloudy water, and reduced chlorine efficiency. Safer and easier to handle than liquid muriatic acid, it is an essential part of any balanced pool maintenance program.

🚩 PRO TIP

Maintaining proper water balance can prevent common problems like scale and can make other products work better. Always test your pool water weekly and keep pH between 7.2–7.6. Adjust pH after balancing total alkalinity for best results — stable alkalinity makes pH much easier to maintain.
