Velda are a premium aquatic brand dedicated to water gardening, they are based in Holland and are not particularly well know in the UK. We are a specialist dealer for all the Velda pond products as we believe that they offer quality solutions. The Clear Control range of pond filters is a proven range in Europe and we believe that when pondkeepers see the quality of these filters the UK will love them too! We have always appreciated the benefits that a pressure filter brings to a pond project: - they can be positioned/buried below the water return area - they can handle high pump flow rates - they are compact However, mainly due to their small size they were never a real option for large ponds, heavily stocked ponds or high waterfalls. The NEW Velda Clear Control 100 changes everything! This filter has a canister capacity of 100 litres - more than twice the nearest competitor.It is also equipped with a seven-position handle switch which means the filter can be simply turned to the Clean position and effectively cleaned/backwashed without removing the lid. Dirty water then exits via the waste outlet.The other position options include: • Back wash valve: Washes away the dirt in the valve • Pond drain: Empties the pond • Filtration: Standard running position • Medicine position: Water runs back into the pond bypassing the filter media • Stop: Pump can be cleaned, whereas the water remains in the filter • Winter: NEW Drops the water within the container by about 2 inches and prevents damage to the rubber sealing ring in severe winter conditions. NOTE: UVC bulb included.
