Wiltec High Performance Pond Clarifier UV light 36 W CUV-236 36 Watt UV light sterilizer Do you have algae problems in your pond? Do the algae multiply themselves under the influence of strong sunlight? - It protects your fish against germs - Safe and good for your fish and plants - Provides clear water - It purifies the pond water without the addition of chemicals - It keeps algae, bacteria and mold formation under control - With universal hose connections The pond water is pressed with a pump through the housing, where it is channelled past the UV-light sterilizer. By means of UVC-radiation of the PL-lamp, harmful bacteria and germs are destroyed and the algae formation remains under control. The UVC-clarifier provides clear pond water within 14 days. You achieve the best result if you combine the UVC-clarifier with a biological filter. When should you use an UVC-steriliser? If there is a reason for assuming a high bacteria level and all your other posibilities have been exhausted then the long-term use of a UVC-clarifier for reducing the bacterial count is highly recommended . UV lamps clarify the water in the pond. Swimming algae proliferate in pond water under the influence of organic polllution very fast if exposed to strong sunlight and colour the water green. This happens especially in spring when the temperature rises and the sunshine duration increases. UVC-pond clarifiers irradiate the water in a flow-through reactor with UV rays.The UV-C radiation destroys the swimmig algae. The algae agglutinate to large particles and ca be easily removed by means of mechanical filtering. Our UVC clarifiers modify the tertiary and the quaternary structure of the algae proteins by means of UV-radiation. This means the destructions of the algae which can be removed from the water. Ocasionally you can hear the argument a UVC-clarifier is unnatural.
