Collection: Fluval UV Sterilizers

One item is listed under Fluval here: the FX UVC In-Line Clarifier. As the name indicates, it is an in-line unit, installed within the plumbing run rather than placed inside the aquarium, which keeps both the unit and its cable clear of the display. With a single unit on the page there is no ladder of sizes to work through, so the question is whether an in-line fitting suits the filter and hose already in service. Check the hose diameter and the free length on the run before ordering.
