AUTO-OFF: automatic safety cut-off when changing lamp Easy to attach using the included fixing bracked Variable installation, no defined installation position or flow direction Accessories: EHEIM UV-C-lamp, fixing unit, ballast with power cable, 2x hose connection taps ø 12/16 mm, 2x hose connection taps ø 16/22 mm Special technology for clean water and healthy fish   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 microorganisms, 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. What you should also know: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.  Torbidity 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.The light source contained in this product is intended exclusively for the disinfection of aquarium water.

Specjalna technologia oczyszczająca wodę i zapewniająca zdrowie ryb W sterylizatorze UV woda z akwarium przechodzi cienką warstwą przed lampą UV-C. Promieniowanie UV-C penetruje wodę zabijając mikroorganizmy, zarodniki glonów i inne małe organizmy. Przy zastosowaniu konwencjonalnej technologii, woda napromieniowywana jest tylko z jednej strony. Tymczasem EHEIM wyposażył urządzenie w odbłyśnik odbijający promieniowanie, dzięki czemu penetruje ono wodę również pod innym kątem. Sterylizator reeflexUV charakteryzuje się znacznie wyższym poziomem parametrów roboczych. Ponadto, w urządzeniu tym uniknięto skomplikowanego systemu przepływu wody. Nie jest ona przekierowywana bocznym obiegiem, tylko trafia bezpośrednio pod lampę. Dzięki temu nie dochodzi do utraty wydajności. Automatyczny wyłącznik gwarantuje optymalny poziom bezpieczeństwa. Ponieważ promieniowanie UV-C może uszkodzić skórę lub oczy, urządzenie wyłącza się natychmiast w przypadku otwarcia. Co jeszcze trzeba wiedzieć: W porównaniu do zwykłej wody liczebność bakterii w wodzie akwariowej jest stosunkowo duża ze względu na jej niewielką objętość. Warto ten parametr obniżyć do normalnego poziomu. Jednak nie można dopuścić do całkowitego wyeliminowania bakterii z akwarium. Sterylizator UV eliminuje tylko bakterie unoszące się w wodzie. Bakterie zasiedlające filtr (patrz: filtracja biologiczna) oraz podłoże zostają oszczędzone. Sterylizator UV bardzo skutecznie usuwa zmętnienie wody spowodowane przez unoszące się w wodzie bakterie lub glony. Generalnie, wzrost liczebności glonów zostaje zahamowany w wyniku eliminacji zarodników. Co do zasady, sterylizatory UV poprawiają stan zdrowia ryb ograniczając ryzyko infekcji. Sterylizatory UV poleca się szczególnie do zbiorników hodowlanych, ponieważ może w nich dochodzić do kolonizacji ikry lub młodych zwierząt, które nie wykształciły jeszcze odpowiedniej odporności przez groźne patogeny. Generalnie, sterylizacja UV w żaden sposób nie zmienia parametrów jakościowych wody.

With EHEIM reeflexUV+e you reduce or eliminate germ contamination and eliminate turbidity in the water. Now with WiFi controls. reeflexUV+e is the WiFi-controlled next step of the proven EHEIM UV clarifier reeflexUV. The principle of the patented reflector technology (with significantly increased germicidal UV-C radiation) has remained the same. While in conventional UV clarifiers the water flows past the UV-C burner via detours, in the EHEIM reeflexUV+e it takes a more direct route. This results in no loss of power and saves energy, being twice as efficient. The reeflexUV+e can be coupled with other products in the EHEIM Digital family and can be controlled via WLAN-enabled devices (smartphones, tablets, notebooks etc.). For example, you can select different modes, determine times and pauses and even switch to booster mode in case of a heavy parasite infestation. The reeflexUV+e should be used to support the filter in order to reduce small organisms (germs, algae spores, etc.) in the aquarium.There are 4 models for aquariums from 300 to 2000 litres. As always, this comes with EHEIM’s “Made in Germany” guarantee, ensuring the best standards in manufacturing and materials.   Advantages of the EHEIM reeflexUV+e Quickly and effectively reduces or eliminates harmful germs (bacteria, fungi, viruses, other pathogens) and infectious swarmers of fish parasites as well as suspended algae in the water Patented reflector technology: The unique arrangement of the UV-C light source and the aquarium water flowing past it, in conjunction with a special reflector, ensures unparalleled efficiency with a low energy input Almost no power loss, as the water is not deflected due to the clarifiers innovative design Excellent results: twice as effective compared to conventional UV clarifiers Also ideal for rearing tanks, as it reduces the risk of infection Bound cleaning bacteria in the filter are preserved, as only floating germs are captured Easy and safe handling and cleaning AUTO-OFF: Automatic safety shut-off when changing lamps Easy mounting due to supplied bracket Variable installation, no defined installation position or flow direction Can be coupled with other products in the EHEIM Digital family (e.g. synchronisation with the aquarium lighting) Controlled via WLAN-enabled devices (smartphone, tablet, notebook, etc.) Easy and intuitive operation Three different modes: "constant", "daily cycle", "smart coupling" Configurable burning duration, time, pauses, etc. Booster mode for combating acute parasite infestations Notification by e-mail when the lamp replacement is due Made in Germany 3 years warranty Suitable for both fresh and marine water Warning: UV-C radiation can cause damage to eyes and skin even in small doses. The light source contained in this product is intended exclusively for disinfecting aquarium water.

The EHEIM reeflexUV+e can be coupled with other products in the EHEIM Digital family (e.g. lighting). It is controlled via WLAN-enabled end devices (smartphone, tablet, notebook etc.) Operation is simple and intuitive. There are three different modes: "constant", " daily cycle" and "smart coupling". Burning duration, time, pauses, etc. can be set individually. There is a booster mode to combat acute parasite infestations. And when a lamp change is due, a message is sent by e-mail. You should also know that:Compared to natural waters, the bacterial concentration in the aquarium is relatively high due to the smaller amount of water. It is important to reduce this and bring it to a natural level. However, the aquarium water cannot and should not be completely germ-free.
