EHEIM ReeflexUV 350 is a compact UV sterilizer designed to improve aquarium water clarity and health by eliminating free-floating algae, bacteria, and parasites. Rated for smaller aquariums, the ReeflexUV 350 features a high-efficiency UV-C bulb and a reflective internal chamber that maximizes exposure, achieving excellent sterilization with minimal dwell time.

It’s easy to install in-line with your filter or pump (fits standard hose sizes) and has a quick-release for simple bulb changes. The “Non WiFi” model operates with a straightforward on/off functionality and indicator light. It’s a plug-and-play solution for clearer, healthier water in freshwater or marine aquariums up to roughly 90 gallons.
