Fluval FX UVC In-Line Clarifier

The Fluval FX UVC In-Line Clarifier connects to your canister filter and uses an energy-efficient 6W UVC bulb to wipe out cloudy and green water, leaving your aquarium crystal clear. It installs in-line on the filter's return, so there is no separate pump or powerhead to add, and it treats systems up to 400 gallons. It pairs perfectly with our Fluval FX and Fluval 07 Series canister filters. Browse more gear in our saltwater and freshwater collections.

How It Works

As water flows past the UVC bulb, ultraviolet light neutralizes the free-floating algae that causes green water, along with waterborne bacteria and pathogens. The result is clearer, healthier water without chemicals. Because it runs in-line off your existing canister filter, setup is simple and it works quietly in the background.
