External Aquarium Filter Fluval 407 — FV-4500, Flow 4500 L/h

Fluval 407 external aquarium filter (FV-4500) is a canister-style filtration unit designed to provide mechanical and biological filtration with a maximum flow rate of 4500 L/h. Intended for freshwater, planted, and community aquariums, this external filter reduces in-tank equipment clutter while offering multi-stage media capacity and dependable circulation to improve water clarity and overall tank conditions.

Advantages

The Fluval 407 combines a high flow rate with a compact external design to deliver efficient water turnover and minimize maintenance intervals. Its multi-chamber canister supports layered filtration media for mechanical debris removal and biological nitrification, allowing flexible customization of media types. The sealed canister construction and integrated quick-disconnect valves simplify service and reduce the risk of spills during cleaning. Quiet operation and consistent flow help maintain stable conditions for fish and plants.

Suitable for

• Freshwater community aquariums
• Planted tanks requiring reliable circulation
• Medium to large aquariums that benefit from external canister filtration
• Setups where reduced in-tank equipment and easier maintenance are desired

Key specifications

• Maximum flow rate: 4500 L/h
• Filtration type: external canister with multi-stage media chambers
• Functions: mechanical and biological filtration
• Suitable aquarium types: freshwater, planted, community
• Service features: quick-disconnect valves and sealed canister design for easier maintenance

How to use

Install the canister filter outside the aquarium on a stable surface below or beside the tank. Connect intake and output hoses to the appropriate fittings and secure them with the provided clamps. Prime and start the unit following the manufacturer's instructions, ensuring hoses are free of air pockets to achieve full flow. Arrange filtration media in the recommended order within the canister to maximize mechanical pre-filtration before biological media. Monitor flow and water parameters regularly and perform planned media cleaning or replacement to maintain filtration efficiency.

Usage recommendations

For optimal performance in planted and community freshwater aquariums, position the output to promote gentle circulation across the tank rather than strong direct current. Check and clean pre-filter foam or mechanical media every 2–4 weeks depending on bioload, and inspect biological media less frequently to preserve beneficial bacterial colonies. When servicing, use quick-disconnect valves to minimize water spillage and re-prime the unit as instructed to restore maximum flow.
