Eheim Reeflex 1500 UV 18w UV Steriliser kills off micro organisms and algae spores

  • Fast and effective reduction of micro organisms in the water
  • Eliminates turbidity caused by algae or bacteria
  • Internally fitted high gloss aluminium reflects the UV-C light and ensures more efficient sterilisation
  • Excellent results with low energy consumption (1.8 times more effective than conventional UV-sterilisers)
  • No performance loss as, using a special design, the water is not redirected
  • Also ideal for breeding tanks as it reduces the risk of infection
  • Cleansing bacteria are safely retained in the filter as only floating organisms are captured
  • Simple, safe maintenance and cleaning
  • AUTO-OFF: automatic safety cut-off when changing lamp
  • Easy to attach using the included fixing bracket

reeflexUV is yet another typical innovation from EHEIM: due to a built-in reflector the micro organism killing UV-C radiation is significantly increased and whereas in conventional UV-sterilisers the water is directed via detours past the UV-C burner, in the EHEIM reeflexUV water it takes the direct route. There is no loss of performance, you need less energy and the level of effectiveness is 1.8 times greater.

reeflexUV should only be used in conjunction with the filter, in order to reduce small organisms (microorganisms, algae spores etc.) in the aquarium.

In a UV-steriliser, the aquarium water is directed as a thin film past a UV-C lamp (burner). The UV-C radiation penetrates the water and kills off micro organisms, algae spores and other small organisms.

Using conventional technology the water is only irradiated on one side. EHEIM on the other hand has built in a reflector, via which the reflected radiation penetrates the water from more sides. Thus reeflexUV achieves a significantly higher performance level.

Furthermore, the EHEIM reeflexUV doesn't have a complicated water flow system. The water is not redirected and flows around the burner without detours. So there is no loss of performance.

The AUTO OFF ensures an optimum level of safety. Since UV-C radiation can cause damage to skin and eyes, reeflexUV switches off immediately when the device is opened.

Compared to normal waters the bacterial count in an aquarium is relatively high due to the small amount of water. It is worth reducing this and bringing it back to a normal level. However, the aquarium water should never be completely bacteria free.

Only floating bacteria in the water are captured by the UV-steriliser. Colonised cleaning bacteria in the filter (compare biological filtration) and bacteria in the gravel substrate are spared.

Turbidity in the water, caused by bacteria or floating algae, is removed very efficiently by the UV-sterilisation. Basically-algae growth is curbed, because the spores are killed off.

UV-sterilisers generally ensure healthier fish, because the risk of infection is reduced. A UV-steriliser is especially recommended for breeding tanks, because dangerous pathogens colonise on eggs or infect young livestock, which don’t yet possess enough power of resistance.

UV-sterilisation in general doesn't cause any kind of changes to the water values.
