If this does not happen, you will experience the phenomenon of a green pond. The irradiation with UV-C light destroys microscopic cells through a chemical bond of the DNA (genetic material). They clump together and are removed from the water cycle by the filter. The size (wattage) of the UV-C lamp to choose depends on your pond volume and surface area. The larger the surface area, the greater the sunlight exposure and the growth of suspended algae. High wattage UV-C devices are ineffective if the circulation is too low. We have often observed this in ponds that were poorly designed. The pond volume should be pumped through the UV-C lamp at least every two hours. We are happy to advise you on which UV-C device is best suited for your pond. UV-C devices should never be operated without water flow. Overheating could damage the device. Caution: UV-C radiation is harmful to the eyes of humans and animals. Never look into UV-C light without appropriate safety goggles. The light should also not shine on the bio-medium!.
