Eheim ReeflexUV 800 Non-Wifi Aquarium UV Sterilizer - 600 Liters Per Hour

EHEIM ReeflexUV 800 is a high-capacity UV sterilizer aimed at large aquariums (up to ~210 gal) that require robust water clarification. It utilizes an 11 W UV-C lamp and a highly reflective internal surface to neutralize water-borne algae, bacteria, and protozoa efficiently. The ReeflexUV 800’s flow-through design has no bypass, ensuring every drop of water is exposed to UV for maximum germicidal effect. Hobbyists use this unit to achieve and maintain pristine water clarity in both freshwater and marine systems, as well as to reduce the spread of diseases in fish populations. Installation is straightforward with the included universal hose connectors, and operation is simply on/off (this is the non-WiFi model). For large tanks experiencing persistent green water or high bioload, the ReeflexUV 800 provides a reliable, low-maintenance solution to improve water quality and visibility.
