EHEIM reeflexUV 2000 — 24W UV Sterilizer Reflector Aquarium 1200-2000L - Eheim

EHEIM reeflexUV 2000 UV Sterilizer — 1.8x Reflector Technology for Aquariums 1,200 to 2,000 Liters

The EHEIM reeflexUV 2000 UV sterilizer is the most powerful model in the standard reeflexUV series. It uses patented polished aluminum reflector technology, making the unit 1.8 times more effective than conventional UV sterilizers. Unlike traditional sterilizers where water is only irradiated from one side, the reeflexUV's integrated reflector redirects UV-C rays to penetrate the water from multiple sides simultaneously, significantly increasing germ elimination rates. Made in Germany.

The reeflexUV 2000 is designed for large freshwater and saltwater aquariums from 1,200 to 2,000 liters (317 to 528 gallons). Its 24-watt UV-C lamp offers a maximum flow rate of 1,500 l/h in sterilization mode (bacteria and parasites) and 3,000 l/h in clarification mode (algae and turbidity). Intended for large reef systems, multi-tank aquariums, and installations requiring high treatment capacity. Water flows directly around the UV-C tube without detours or diversions, which eliminates any loss of performance.

EHEIM Reflector Technology

The high-gloss polished aluminum internal reflector is the distinctive technology of the reeflexUV. In a conventional UV sterilizer, UV-C rays only irradiate the water from one side. The EHEIM reflector redirects the radiation so that it penetrates the water from multiple sides, multiplying germicidal efficiency by 1.8 with the same energy consumption. This technology is exclusive to EHEIM.

AUTO-OFF Safety

UV-C rays are harmful to skin and eyes. The integrated AUTO-OFF system automatically cuts power as soon as the device is opened, ensuring safe handling during maintenance and lamp replacement.

reeflexUV 2000 vs reeflexUV 2000+e

The standard reeflexUV 2000 and the reeflexUV 2000+e share the same 24W power and treatment capacities. The +e version adds WiFi control, three programmable modes (constant, daily cycle, smart coupling), an anti-parasite booster mode, and email notifications for lamp replacement. The standard model is the ideal choice if you don't need WiFi control and want simple, reliable operation.

Installation

Install the reeflexUV 2000 on the pressure side (return) of your external filter or circulation pump. The unit comes with connectors for 12/16 mm and 16/22 mm hoses, compatible with most EHEIM external filters and other brands. Installation is variable: no imposed position or flow direction. The included mounting bracket allows for easy installation.
