Product description

Fluval FX4 is a high performance canister filter with many outstanding features designed to make aquarium fish keeping easier and more convenient than ever. This super capacity yet compact canister filter has a pump output of 700 gallons of water and has a filter circulation of 450 GPH, which both work to produce cleaner and healthier results. Filtering material can easily be placed in a removable stack of media baskets, which is at the heart of Fluval's multistage filtration. The baskets are precision-engineered to eliminate water by-pass, making filtration more efficient. The baskets can hold a total of 1 gallon of media and can be stacked in the precise combination of layers that will work best for your aquarium. Each one is lined with a foam insert for effective mechanical pre-filtering. Instant-release T-handles let you lift and separate the baskets quickly and easily, making routine maintenance simpler. FX4 also features Smart Pump Technology, which provides optimal filter performance. This advanced technological feature employs an electronic circuit board that continually monitors the pump. Impeller speed and force are constantly measured to ensure powerful output and energy efficiency. It also manages the filter's self-starting feature and evacuates air that may enter or build up within the filtration system. On a 12-hour cycle, the pump will pause and allow trapped air to escape, ensuring the best filtration efficiency. Only 16.5 inches in height, FX4 fits under most aquariums.

Fluval first broke onto the aquatic scene in 1975 by introducing the world’s first 3-stage filter with synchronous motor technology. Since then, Fluval has built a legacy around this pioneering spirit, relentlessly adapting in a changing world to launch innovative aquarium products. Fluval’s mission is not just about building products that mimic the natural world, but inspiring aquarists of all skill levels to enjoy and respect the hobby for generations to come.

Reviewed in the United Kingdom on 31 March 2019
This thing is awsome .... I bought the all pond solutions 1000ef with the booster about 6 months ago. Works fine but I wanted more filtration but couldn't afford one of these fx4 then I finally bought it !! I'm telling you now the flow rate on this thing is brilliant puts my pond solutions to shame.. just be careful when you chop the pipe in half make sure you measure to your tank size apart from that when I plugged it in it instantly primed itself !! Then the power is amazing without doubt this is well worth the money. It isn't noisy at all dont listen to other reviews the is quiet powerful and definitely worth it
