Slow-dissolving 250 g multifunctional chlorine tablets for long-lasting pool disinfection. Helps prevent algae, improves water clarity and supports balanced, hygienic water. Ideal for regular maintenance of domestic pools.
Multifunctional chlorine tablets from Gre are designed to deliver complete, long-lasting and
highly effective pool water treatment. Each slow-dissolving 250 g tablet gradually releases chlorine into the
water, ensuring continuous disinfection and helping maintain a clean, clear and hygienic swimming environment.
This product is ideal for pool owners who want reliable water care with minimal daily maintenance.
The advanced multifunctional formula combines several essential treatment actions in one tablet: it disinfects
the water by eliminating bacteria and microorganisms, prevents algae growth, improves water clarity and supports
balanced water chemistry. These combined effects help reduce the need for corrective treatments and ensure
stable water quality even during periods of high temperatures, intense sunlight or heavy pool usage.
Thanks to their slow-dissolving structure, the tablets provide a steady and controlled release of chlorine,
avoiding sudden concentration spikes and ensuring consistent performance. When used together with proper
filtration and pH regulation, they significantly improve overall water quality and reduce the frequency of
manual interventions.
