Pontec MultiClear Set 20000 - Flow-Through Filter

The Pontec MultiClear Set 20000 is a compact, ready-to-connect flow-through filter for ponds up to 20,000 litres without fish (10,000 L with fish). It combines mechanical-biological filtration and an 18 W UVC clarifier for clear, healthy, and guaranteed water. 2-year warranty.

⚠️ Note: The pump and connection hose are not included in the set and must be purchased separately.

💡 Expert tip: The UVC clarifier is most effective when water flows slowly through the UV chamber: do not oversize the pump compared to the recommended flow rate to maximize UV exposure time and algae elimination. The ability to bury the filter by ⅓ is not just aesthetic: it reduces temperature fluctuations of the water during filtration, improving biological stability. Replace the UVC lamp every 12 months even if it still appears to be working, because UV effectiveness diminishes before the light visually goes out. Caution with koi carp: koi produce a very high organic load — for a pond with koi, the effective filtering capacity is significantly reduced; it is recommended to halve the maximum recommended volume or combine with a dedicated pre-filter.
