Haviland DuraChlor 56 Granular Pool Chlorine Granules 10 lb

The Haviland DuraChlor 56 Granular Stabilized Chlorine Granules (10 lb) provide potent, fast-dissolving pool sanitation with 56% available chlorine. Formulated for daily maintenance in all pool types including vinyl-lined pools, these near-neutral pH granules are completely soluble, making them an ideal choice for routine chlorination and algae control in both residential and commercial pools.

🚩 PRO TIP

Broadcast granules directly over the pool surface with the pump running. Apply 2.5 oz per 10,000 gallons daily to maintain 1–3 ppm free chlorine. Adjust pH to 7.2–7.6 and total alkalinity to 125–175 ppm before dosing. Never pre-mix with other chemicals.
