Our all-in-one tablets have multiple beneficial effects on your pool. Disinfectant against viruses; Bactericide to kill bacteria, Algaecide which kills and prevents growth of algae, Stabiliser to help last longer and a clarifier, which contains flocculant designed to help clump foreign tiny debris particles together to get caught easily in the filter to keep the water looking crystal clear. Before Use Please ensure your water levels are ‘balanced’ before usage as per pool or hot tub guidelines. Slow release chlorine tablets are designed to maintain chlorine levels. How to Use Simply put desired amount of tablets into dispenser, monitor the chlorine levels until a constant level has been achieved. Top up when the levels are low and always use same tablet type or brand when replacing tablets or wash out thoroughly first. Check your water balance (chlorine and pH) regularly with a test kit to ensure safe bathing and to adjust the dispenser flow settings to keep a steady chlorine level. Ideal levels for most set ups - Chlorine residual between 2-3mg/l and pH between 7.2 – 7.6.
