Fluval FX UVC In line Clarifier 6 Watt

The FX UVC In-Line Clarifier quickly and easily connects to all canister filters to eliminate suspended algae for a clean and clear aquarium. With unique CCFL technology, the FX UVC bulb runs cooler to last up to 2X longer than traditional lamps. It attacks green and cloudy water by applying powerful, DNA-destroying light emissions at a precise 253 nanometer wavelength. This natural process is chemical-free and will not affect beneficial, surface-dwelling bacterial colonies that are already established. Say goodbye to cloudy and green water forever!
