The Fluval UVC In-Line Clarifier is a compact and efficient solution for maintaining clear aquarium water by eliminating suspended bacteria and algae that cause cloudy or green water. Designed to be installed directly into your existing filtration line, it provides effective ultraviolet clarification without the use of chemicals and without disrupting beneficial bacterial colonies.

Using Fluval’s Cold Cathode Fluorescent Lamp (CCFL) technology, the unit delivers powerful UVC light emissions that target and neutralise unwanted microorganisms within the water column. The CCFL system runs cooler than traditional UV lamps and offers an extended operational life of up to 30,000 hours. An included 4–24 hour timer allows for controlled, energy-efficient operation.

Its compact, multi-directional design makes installation straightforward, fitting neatly within aquarium cabinetry and connecting easily to compatible canister filter systems. Suitable for freshwater, marine and turtle aquariums, this unit supports improved water clarity while helping reduce ongoing maintenance. Please note: supplied without the original box.
