Product Description

The Fluval FX4 High Performance Canister Filter took the excellence from the 406 and FX6 canister filter, creating the FX6's 'little brother'. It fills the gap between these two models providing the perfect selection for freshwater and marine aquariums of up to 250 gallons in size. With its European ingenuity, it is carefully designed to maintain the cleanest and clearest water while improving performance, simplifying operation and optimizing your hobbyist experience.

The outstanding refined multi-stage filter produces a powerful 700 gph while operating with 30 watts of electricity; However, with media this translates to 450 gph of effective filtration. While water is being forced through, an anti-clog, telescopic strainer is intended to ensure a continuous water flow; thus, assuring that filtered water is being returned to the aquarium from the dual, multi-directional output nozzle. This can be adjusted to customize specific water flow patterns.

Pump performance is optimized by continuously being monitored by advanced Smart Pump microchip technology. This accurately measures impeller force and speed, assuring that a powerful output, super-quiet operation and energy efficiency is maintained. A self-starting, just-add-water plug in is incorporated, where no priming is necessary. This is then taken over by the Smart Pump. There is a trapped air auto-evacuation which automatically shuts down the pump every 12 hours to ensure optimal performance.

The Fluval FX4 features a 3.9 L (1 gal) media capacity, along with all of the required media included to fill up the customizable and stackable media baskets, each lined with mechanical-pre-filtering foam inserts. These baskets are carefully structured to successfully eliminate bypass, guaranteeing complete filtration.

There are provided Aqua-Stop valves with a leak-proof Click-Fit attachment system, as well as valves which are positioned at convenient 45-degree angle for easy installation and rotation. Not only is installation simple, but maintenance and flushing of the canister is a breeze as well by using the Utility Valve and drain hose. This compacted canister filter has rubber feet to absorb sounds from any vibrations and has a height of 16.5", which allows you to easily set it under most aquariums.

The Fluval FX4 High Performance Canister Filter, provides the option to attach hosing to the output (kit sold separately) and Smart Pump, in order to simplify water changes. This rids the terrible experience of having to carry heavy buckets of water each time a water change in required.

Backed by a 3 year manufacturers warranty.
