EHEIM ReeflexUV 2000+e is the ultimate UV sterilizer for expansive aquatic systems, now with smart connectivity. This flagship model offers maximum water clarification power, suitable for the largest aquariums or small ponds, and its “+e” functionality means you can supervise and adjust it remotely. You’ll get real-time information through the EHEIM digital app – for example, confirmation that the unit is running or notifications when the UV bulb should be replaced – and you can turn the sterilizer on/off or set schedules from your device. Mechanically, it retains the highly efficient UV design: fast-flow exposure without a bypass, reflective interior, and effective germicidal elimination of waterborne algae and pathogens. For public aquariums, fish rooms, or serious hobbyists, the ReeflexUV 2000+e provides industrial-strength water purification along with the peace of mind and ease-of-use that comes with electronic integration.
