Collection: Fluval UV Sterilizers

A single Fluval item is listed here: the FX UVC In-Line Clarifier. The name gives away the fitting - it goes into the plumbing run instead of sitting inside the aquarium, which keeps the unit and its cable clear of the display. With one unit on the page there is no ladder of sizes to work through, so the decision comes down to whether an in-line fitting suits the filter and hose already running. Measure the hose diameter and the free length on the run before ordering.
