This impeller assembly is a genuine replacement part specifically designed for Fluval FX5 and FX6 external canister filters, ensuring perfect fit and reliable long‑term performance. The impeller is the rotating magnetic component that drives water through your filter, making it a critical part of your aquarium’s filtration and circulation system.

Features and benefits

• Genuine Fluval spare part for FX5 and FX6 canister filters, ensuring proper performance and warranty-safe maintenance.

• Magnetic impeller assembly supplied complete with bushing and O‑ring, so most common wear parts are replaced in one simple step.

• Restores strong, consistent flow when your filter output has dropped due to a worn or damaged impeller.

• Helps reduce vibration and buzzing noises that often occur when an old impeller shaft or magnet is worn.

• Regular impeller replacement is recommended to prolong the life of the motor and reduce the risk of leaks around the seal area.

Ideal for beginner aquarists

Beginner aquarists often experience reduced flow or rattling noises from their canister filter and may worry that the entire unit has failed. Replacing the impeller is usually a straightforward and cost‑effective solution that restores performance without replacing the whole filter. With only basic tools and careful handling, most hobbyists can perform this maintenance themselves by following the FX‑series manual and a step‑by‑step guide or video.

Basic installation guidance (general)

• Disconnect the filter from the power supply and close all valves before starting work for safety.

• Remove the motor/impeller housing from the canister lid as described in the FX‑series instructions, usually by undoing the retaining screws and gently pulling the motor block free.

• Carefully pull out the old impeller, noting the position of the bushing and O‑ring, then install the new impeller assembly in the same orientation.

• Ensure the O‑ring is seated correctly, reassemble the motor block onto the filter head, and tighten all screws evenly so the housing sits flat and sealed.

(Always refer to the official Fluval FX‑series instruction manual and your specific filter’s documentation for exact steps.)
