Fluval In-Line 3W UVC Clarifier

Keep your aquarium water crystal clear with the Fluval UVC In-Line Clarifier, designed for quick and easy connection to most canister filter setups. Using powerful CCFL (Cold Cathode Fluorescent Light) technology, it eliminates suspended bacteria and algae that cause cloudy and green water, all without chemicals or maintenance. Unlike traditional clarifiers, this unit does not harm beneficial, surface-dwelling bacteria essential to a healthy ecosystem.

With a compact design that fits neatly inside aquarium cabinetry, the Fluval UVC Clarifier maximizes water contact time by redirecting flow up, down, and around the bulb for highly effective clarification. The long-lasting CCFL bulb runs cooler and lasts up to 30,000 hours (3x longer than standard UVC bulbs), and is easily replaceable when needed.
