Weipro UV sterilisers can eliminate single cell algaes giving crystal clear water in aquariums and ponds. They can also help control bacteria and other water borne parasites and decreases the risk of fish acquiring infections. The controlled water flow within the Weipro UV and its large volume ensure maximum efficacy. The water is directed in a spiral path around the quartz tube resulting in more efficient use of the UV radiation than in standard units. The inlet and outlet fittings can be rotated through 360° for easy mounting at any angle. Weipro UV sterilisers are available with a 10 m rubber cable and high frequency electronic ballast, for garden ponds, salt and fresh water aquariums.The electronic ballasts increase the lifetime and the efficacy of the UV lamps.
