The UV-C radiation penetrates the water, eliminating microorganisms, algae spores, and other tiny organisms. Traditional technology typically irradiates the water from just one side. However, EHEIM incorporates a reflector that allows the reflected radiation to penetrate the water from multiple angles, achieving significantly higher efficiency. Furthermore, the EHEIM reeflexUV features a straightforward water flow system, allowing water to flow around the burner directly without any detours, eliminating performance loss. The AUTO OFF feature enhances safety, as UV-C radiation can be harmful to skin and eyes; the reeflexUV turns off immediately when the unit is opened. It’s important to note that the bacterial count in an aquarium is typically higher than in regular water due to the limited volume. Therefore, it’s beneficial to lower this count back to a normal level. However, the aquarium water should never be completely free of bacteria. Only suspended bacteria in the water are captured by the UV sterilizer, while established cleaning bacteria in the filter and those in the gravel substrate remain unharmed. Turbidity caused by bacteria or floating algae is efficiently removed through UV sterilization, effectively curbing basic algae growth by killing off their spores. UV sterilizers contribute to healthier fish by reducing the risk of infections. A UV sterilizer is particularly recommended for breeding tanks, as hazardous pathogens can settle on eggs or infect young fish that lack sufficient resistance. Generally, UV sterilization does not alter water values. The light source included in this product is solely intended for disinfecting aquarium water.

EHEIM reeflexUV effectively minimizes microorganisms in the water and tackles turbidity more efficiently than ever before. This product exemplifies EHEIM's commitment to innovation: thanks to its integrated reflector, the UV-C radiation that eliminates microorganisms is significantly amplified. Unlike traditional UV sterilizers that direct water around the UV-C burner, EHEIM reeflexUV allows water to take a direct path. This design ensures no performance loss, requires less energy, and boasts a level of effectiveness that is 1.8 times higher. It is essential to use EHEIM reeflexUV alongside a filter to effectively reduce small organisms (such as microorganisms and algae spores) within the aquarium. Available in 5 models, it caters to aquariums ranging from 80 to 2000 liters.

You can expect excellent results with minimal energy consumption (1.8 times more efficient than traditional UV sterilizers). There’s no loss of performance since the special design prevents redirection of water flow. It's also perfect for breeding tanks, as it lowers the risk of infections. Beneficial bacteria are safely retained in the filter since only floating organisms are captured. AUTO-OFF feature: automatic safety shut-off when changing the lamp. Easy installation with the included fixing bracket. Versatile setup, allowing for no specific installation position or flow direction. Accessories included: 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 sterilizer, aquarium water flows in a thin layer past a UV-C lamp (burner). The UV-C radiation penetrates the water, killing microorganisms, algae spores, and other tiny organisms. Conventional methods irradiate water from only one side. In contrast, EHEIM incorporates a reflector that enables the reflected radiation to penetrate the water from multiple angles, achieving much greater performance levels. Additionally, the EHEIM reeflexUV avoids complex water flow systems. Water flows around the burner without unnecessary detours, ensuring no performance loss. The AUTO OFF feature enhances safety; since UV-C radiation can be harmful to skin and eyes, the reeflexUV automatically shuts off when the device is opened. **What you should know:** Aquarium water tends to have a relatively high bacterial count due to its limited volume. It's beneficial to manage this and maintain it at normal levels, but the water should never be entirely free of bacteria. The UV sterilizer captures only floating bacteria. Established cleaning bacteria in the filter (as seen in biological filtration) and those in the substrate are preserved. Turbidity caused by bacteria or floating algae is efficiently removed through UV sterilization, thereby curbing algae growth by killing their spores. UV sterilizers generally promote healthier fish by decreasing the risk of infections. They are particularly recommended for breeding tanks, as harmful pathogens can settle on eggs or infect young fish that lack sufficient resistance. Notably, UV sterilization does not alter water parameters. The light source in this product is designed solely for disinfecting aquarium water.

The EHEIM reeflexUV effectively diminishes microorganisms in your aquarium water while improving clarity like never before. This product showcases EHEIM's commitment to innovation: equipped with a built-in reflector, the UV-C radiation that eliminates microorganisms is significantly enhanced.

Advanced Technology for Clean Water and Healthy Fish Within a UV sterilizer, aquarium water is guided as a thin film past a UV-C lamp (burner). The UV-C radiation penetrates the water, effectively eliminating microorganisms, algae spores, and other tiny organisms. Conventional technology typically irradiates the water from only one side. In contrast, the EHEIM design incorporates a reflector that allows the reflected radiation to penetrate the water from multiple angles, achieving a significantly higher performance level. Additionally, the EHEIM reeflexUV features a straightforward water flow system. Water flows around the burner directly without unnecessary detours, ensuring no loss of performance. The AUTO OFF function enhances safety, as UV-C radiation can harm skin and eyes; therefore, the device automatically shuts off when opened. Important Information: In comparison to normal water, the bacterial count in an aquarium is relatively high due to the limited water volume. It is beneficial to lower this count to a normal level, but the water should never be completely free of bacteria. Only floating bacteria in the water are eliminated by the UV sterilizer, allowing colonized cleaning bacteria in the filter (as seen in biological filtration) and bacteria in the substrate to remain unaffected. Turbidity caused by bacteria or floating algae is effectively cleared through UV sterilization, thus inhibiting algae growth as spores are eradicated. Overall, UV sterilizers promote healthier fish by reducing the risk of infection. They are especially recommended for breeding tanks, where harmful pathogens can attach to eggs or infect young fish that may lack adequate resistance. UV sterilization does not alter water parameters. The light source in this product is specifically intended for the disinfection of aquarium water.

Easy to install with the included fixing bracket; variable installation with no specific position or flow direction. **Included 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 sterilizer, aquarium water is channeled as a thin film past a UV-C lamp (burner). The UV-C radiation penetrates the water, effectively eliminating microorganisms, algae spores, and other minute organisms. Unlike traditional technology, which only irradiates one side, EHEIM’s built-in reflector allows the reflected radiation to penetrate the water from multiple angles, resulting in significantly enhanced performance. Moreover, the EHEIM reeflexUV has a straightforward water flow system. The water flows directly around the burner without detours, preventing any loss of effectiveness. The AUTO OFF feature also provides optimal safety, as UV-C radiation can be harmful to skin and eyes; the system shuts off immediately when the unit is opened. **What you should also know:** The bacterial count in an aquarium is relatively high due to the limited volume of water, making it beneficial to reduce this level without eliminating all bacteria entirely. The UV sterilizer captures only floating bacteria; established cleaning bacteria in the filter (as part of biological filtration) and those in the substrate remain unharmed. Turbidity caused by bacteria or floating algae is efficiently cleared away through UV sterilization, effectively curbing algae growth by killing off spores. UV sterilizers generally promote healthier fish by lowering the risk of infection. They are particularly recommended for breeding tanks, as harmful pathogens can latch onto eggs or infect young fish that lack adequate resistance. UV sterilization does not alter water quality parameters. The light source in this product is solely intended for disinfecting aquarium water.

Users can customize burning duration, timing, pauses, and more. The booster mode is specifically designed for acute parasite infestations, and notifications are sent via email when it's time to replace the lamp. It’s important to note that bacterial concentrations in aquariums tend to be higher than in natural waters due to the smaller volume of water. It is crucial to reduce this concentration to a natural level, but completely germ-free water is neither achievable nor advisable. The UV clarifier captures only those germs that are freely floating in the water, sparing the bound purification bacteria in the filter and substrate. UV clarification effectively removes water turbidity caused by bacteria or floating algae. Essentially, it curbs algae growth by destroying spores. Overall, UV clarifiers promote healthier fish by decreasing the risk of infection, and they are particularly recommended for rearing tanks where young fish and eggs are vulnerable to harmful pathogens. UV clarification generally does not alter water quality parameters.
