EHEIM reeflexUV 500 — 9W UV Sterilizer Reflector Aquarium 300-500L - Eheim

EHEIM reeflexUV 500 UV Sterilizer — 1.8x Reflector Technology for 300 to 500 Liter Aquariums

The EHEIM reeflexUV 500 UV sterilizer uses patented polished aluminum reflector technology that makes the unit 1.8 times more efficient than conventional UV sterilizers. Unlike traditional sterilizers where water is irradiated from only one side, the reeflexUV's integrated reflector redirects UV-C rays to penetrate the water from multiple sides simultaneously, significantly increasing germ removal rates. Made in Germany.

The reeflexUV 500 is designed for freshwater and saltwater aquariums from 300 to 500 liters (79 to 132 gallons). Its 9-watt UV-C lamp offers a maximum flow rate of 400 l/h in sterilization mode (bacteria and parasites) and 800 l/h in clarification mode (algae and turbidity). Water flows directly around the UV-C tube without detours or deviations, which eliminates any performance loss related to water path.

EHEIM Reflector Technology

The internal high-gloss polished aluminum reflector is the distinctive technology of the reeflexUV. In a conventional UV sterilizer, UV-C rays only irradiate 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.

Installation

Install the reeflexUV 500 on the pressure side (return) of your external filter or a circulation pump. The device 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.

Included in the box

9W UV-C lamp, mounting bracket, ballast with power cord, 2x ø 12/16 mm hose fittings, 2x ø 16/22 mm hose fittings.

Frequently Asked Questions

Is the EHEIM reeflexUV 500 compatible with a saltwater reef aquarium?

Yes, the reeflexUV 500 works in both freshwater and saltwater. For a 300 to 500 liter (79-132 gallon) reef aquarium, this is the recommended model. Ensure that the flow rate does not exceed 400 l/h for optimal sterilization effect.

What is the difference between the reeflexUV 350 and the reeflexUV 500?

The reeflexUV 350 (7W) is designed for aquariums from 80 to 350 liters with a sterilization flow rate of 200 l/h. The reeflexUV 500 (9W) covers aquariums from 300 to 500 liters with a doubled sterilization flow rate of 400 l/h. For an aquarium over 300 liters, the 500 model is the appropriate choice.

How to install the reeflexUV 500 with an EHEIM external filter?

Install the reeflexUV on the pressure side (outlet) of the external filter, between the filter and the aquarium. Connect the 12/16 mm or 16/22 mm hoses (both sizes of connectors are included). The device can be installed in any position and flow direction.
