Eheim ReeflexUV 500 Non-Wifi Aquarium UV Sterilizer - 400 Liters Per Hour

EHEIM ReeflexUV 500 is a powerful ultraviolet sterilizer for medium-sized aquariums (up to ~130 gal) that quickly clears green or cloudy water. Using a 7 W UV-C lamp and EHEIM’s reflective housing, the ReeflexUV 500 destroys suspended algae and harmful microorganisms as water passes through, leading to visibly clearer water and a healthier aquatic environment. Its efficient design means a higher flow rate can be sterilized compared to conventional UV units of similar wattage. This “Non WiFi” version is simple to operate just connect it inline with your canister filter or pump using the hose barbs, plug it in, and it will continuously treat the water. Regular use helps prevent algae blooms and can reduce disease pathogen counts, supporting overall fish and coral health. The device itself is compact and fully sealed, with a long-lasting UV bulb that is easy to replace when needed.
