Fluval FX4 External Filter Description

High-Performance Filtration for Large Aquariums

The Fluval FX4 External Filter delivers powerful, multi-stage filtration in a compact design, ideal for aquariums up to 1000 litres (250 US gallons). As a compact version of the highly-regarded FX6, the FX4 combines robust performance with advanced technology, offering aquarium owners superior filtration and ease of maintenance.

Fluval FX4 External Filter Key Features

  • Multi-Stage Filtration: Pumps an impressive 700 gallons (2650 L) of water per hour, delivering efficient, thorough filtration for large aquariums.
  • Smart Pump™ Technology: Equipped with advanced microchip technology, Smart Pump™ continuously monitors and optimises pump performance for maximum efficiency.
  • Self-Starting Functionality: Simply add water, plug in, and the Smart Pump™ will take over, automatically expelling trapped air every 12 hours to maintain peak performance.
  • Effortless Water Changes: The FX4’s innovative design eliminates the need for heavy bucket handling. Attach hosing to the output valve (hose kit sold separately), and the Smart Pump™ manages water changes with ease.
  • Removable, Stackable Media Baskets: The basket-in-basket design prevents water bypass, holding up to 1 gallon (3.9 L) of filter media for maximum filtration. All mechanical, chemical, and biological media are included.
  • Leak-Proof Aqua-Stop Valves: With a Click-Fit attachment system, the valves are positioned at a convenient 45-degree angle for quick installation and rotation.
  • Anti-Clog Strainer: A telescopic, anti-clog strainer ensures a continuous water flow, helping prevent maintenance interruptions.
  • Customisable Flow with Multi-Directional Output Nozzles: Fully adjustable nozzles allow you to create personalised water flows tailored to your aquarium’s setup.
  • Utility Valve with Drain Hose: For easy maintenance and flushing of the canister, reducing time spent on upkeep.
  • Quiet Operation: Rubberised feet minimise vibration for quiet, efficient performance.
  • Compact Design: At 16.5" tall, the FX4 is compact enough to fit under most aquarium cabinets, providing flexibility in aquarium setups.
  • Made in Italy: Crafted with quality and durability for both freshwater and saltwater aquariums.

Read about what our customers have to say!

  • Lovely to have an independent pet supplies store offering such a choice of quality products. Friendly and knowledgeable staff with great customer service. Received great advice to get my dogs onto a food which worked well for them. 5 Stars!
    5/5 Kelly Clarke
  • I just love this store, I have been in a few times now, always give great advice on my puppy, and when things didn't agree with him, they always took the returns, and advised us on other products that might suit better. And we did, Thank you so much for all your help and I will be seeing you soon.
    5/5 Kevin Grimes
  • Brilliant service from amazing staff! Everyone there has a lot of knowledge regarding what food to give even what ingredients in the food would be good/bad for each animal. Or what toys are safe for your animal. Very friendly and helpful! Definitely the best pet shop in the area!5/5 Caera Dennehy
