CrystaLux 4-in-1 Multifunctional Chlorine Tablets provide convenient routine water care for hot tubs, spas and small swimming pools. Each compact 20g tablet dissolves slowly, gradually releasing chlorine to help maintain the required sanitiser level between regular water tests. The multifunctional formula combines four key water-care actions: routine chlorine sanitisation, algae control, water clarifier and stabilisation against chlorine loss caused by sunlight. This helps maintain clean, clear and properly treated water without requiring several separate everyday treatments. Supplied in a substantial 5kg resealable tub containing approximately 250 tablets, CrystaLux 20g Chlorine Tablets are ideal for regular seasonal maintenance. Their smaller size allows more flexible dosing than standard large pool tablets, making them particularly suitable for hot tubs, spas and lower-volume swimming pools. Use the tablets with a suitable floating dispenser or compatible chlorine feeder. Never place chlorine tablets directly onto pool or spa surfaces. Only use them in a skimmer basket where permitted by both the product label and the equipment manufacturer’s instructions. Test the water before dosing. Maintain free chlorine at 3 to 5 ppm in hot tubs and spas or 1 to 3 ppm in swimming pools, with the pH between 7.2 and 7.6. As an initial dosing guide, use 1 tablet per 1,000 litres in hot tubs and spas or 1 tablet per 2,000 litres in swimming pools. Retest every 2 to 3 days and adjust the dispenser opening or tablet quantity as required. Water temperature, sunlight, bathing load and weather conditions can affect chlorine demand. Always read and follow the product label before use.
