Fast‑dissolving chlorine granules for quick and effective pool water disinfection. Ideal for shock treatments and rapid correction of chlorine levels. Helps eliminate bacteria, prevent algae and restore clear, hygienic water.
Quick-dissolving chlorine granules from Gre are designed for rapid and highly effective pool
water disinfection. Their fast‑acting formula allows chlorine to disperse immediately upon contact with water,
making them ideal for situations where quick corrective action is required. These granules help restore clean,
clear and hygienic water in a short time, ensuring a safe swimming environment for the whole family.
Thanks to their high solubility, the granules work efficiently both for routine maintenance and for shock
treatments after heavy pool usage, storms, contamination or sudden drops in chlorine levels. They effectively
eliminate bacteria and microorganisms, prevent algae formation and improve overall water clarity. This makes
them an essential product for maintaining stable and healthy pool water throughout the season.
The granules can be applied directly to the pool water (following proper dilution) or added through the skimmer,
ensuring quick distribution and immediate action. When combined with correct pH regulation and proper filtration,
they significantly enhance water quality and reduce the need for frequent corrective treatments.
