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! Br we have always appreciated the benefits that a pressure filter brings to a pond project br they can be positioned buried below the water return area br they can handle high pump flow rates br they are compact br 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! Br this filter has a canister capacity of 100 litres more than twice the nearest competitor. Br 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. Br the other position options include br • back wash valve washes away the dirt in the valve br • pond drain empties the pond br • filtration standard running position br • medicine position water runs back into the pond bypassing the filter media br • stop pump can be cleaned, whereas the water remains in the filter br • winter new drops the water within the container by about 2 inches and prevents damage to the rubber sealing ring in severe winter conditions. Br br note uvc bulb included.
