Ocasionally you can hear the argument a UVC-clarifier is unnatural. Although this is right in principle, the statement is not convincing as a counter-argument, because from this point of view every pond filter or the whole aquarium is "unnatural". Fish kept with a clarifier are said to grow soft and fall ill immediately after being put into other water. Firstly, that is not true, and secondly it could also be argued that a biological pond filter is harmful and a a relatively high nitrite content would contribute to the fish's strengthening. Quite the opposite. In fact a UVC-clarifier helps balancing the natural biotope of the aquarium environment.

The life span of the UVC-light source varies between 7.000 and 10.000 operating hours. We recommend changing the light source and cleaning the quartz glass of the UV-lamp at the start of the season, when the water temperature of your pond rises. The flowing water is purged of harmful bacteria and germs. The reduction of germs has no negative effect on the pond's microclimate because bacteria settle themselves on stones, the filtration surface and in the whole pond system for reducing pollutants and they can reproduce themselves. The UV-lamp can maintain the total microbial content of the water in near -natural proportions.

The water circulates through the two inlets of the UVC-clarifier and in the process all impurities like algae, bacteria or parasites are reduced. The more this circuit is maintained the more effective is the germ reduction.
