SunSun CUV-318 Pond Clarifier Water Clarifier Light Filter 18W

Do you have algae problems in your pond? Do the algae multiply themselves under the influence of strong sunlight?

• 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 mould formation under control
• With universal hose connections

The pond water is pressed with a pond pump through the housing, where it is channelled past the UV-light steriliser. 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.

A special insert in the inner housing of CUV-300 (without helix) ensures that the water flow moves in a spiral course around the UVC lamp. Consequently, the exposure time to the UV radiation of the water to be clarified is twice increased.
At the same time, SunSun has installed a stainless-steel mirror, which ensures that the unused UV light is reflected. Light that is not absorbed directly is mirrored in the pond water and can act again there. Thus, the contact time of the water to be clarified and the UVC radiation as well as the intensity of this is more than doubled.

If compared with similar devices with reflector technology, this new model is not susceptible to sediments and dirt of the reflector, which reduces significantly the cleaning work.

Regarding koi ponds, each m³ of pond water needs a 3-W power of the UV steriliser.

If there is a reason for assuming a high bacteria level and all your other possibilities 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 pollution very quickly 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 swimming algae. The algae agglutinate to large particles and can 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 by pond filters.

Occasionally, you can hear the argument that a UVC clarifier is unnatural. Although this is right in principle, the statement is not convincing as a counterargument, 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 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 microclimate of the pond 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.

SunSun UVC-devices are cheap for all performance areas.
All UVC water clarifiers are delivered with light source and stepped hosetails.

• Wall mount
• Long working life
• Special UV lamp confers the clarifier a long life span

Mounting:
According to the VDE Directive, all electrical devices must be installed at 2-m safety distance from the water.

Please note: As this CUV clarifier is structured symmetrically, the connecting pipes can be used as inlets as well as outlets.
