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 removal of the lid. Dirty water then exits via 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 inthe 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 this is one of our 'price checked' products we believe that as a main velda dealer we offer the best price in the uk. Br velda are held in the same regard in europe as our other premium brand oase. If you are after a large, high quality filter then we have no qualms in recommending clear control filters. Br br note uvc bulb included.
