## 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.

Review: The best you can get - The best filter ever had in 20 years
Review: What to write about an excellent product - Very good product. But bit pricey but you get what you pay for. Cleans the tank in jiffy. If you have a large tank then this is a nice product. You can also use your own medias along with provided along with the product. The medias provided along with the product is more than enough. I use it in a four feet tank and FX4 approximately cycles the tank 8 time as per my calculation. This is more than enough for the cichlid tank in which I have seeded this FX4.

## Questions & Answers

**Q: How is the longevity of the FX6 compared to other filters people have owned? (primarily Eheim). I will be using it in a turtle tank if that matters...**
A: I've been using the Fluval FX5 on my 100 gallon red eared slider turtle tank for about 12 years now. It's worked flawlessly over the years. I'm about to replace it with the FX6 due to various things starting to get worn out. So yes it does have pretty good longevity.

**Q: I have a 40 gallon tank for two read eared sliders. Would this filter be too strong or just right for my tank? Also, does it come with the hosing?**
A: I've got it on a 55 gallon and it works fine! With turtles you want at least 3 times the filtration so 40 gallons of water needs a 160 gallon rated filter or stronger. Also it is recommended that you house your turtles separately as they are going to grow to be 8-12 inches long and are solitary in the wild! I recommend you join red ear slider turtle owners resto group on Facebook and they will have all the information on best diet best filters and best tanks for your turtles!

**Q: I am sitting up a 75 gallons tank in my office i don't want to clean it a lot what fluval pump would you suggest**
A: Frequent water changes aren’t a necessity if you set your tank up accordingly. Look up low maintenance/ self sustaining and see for yourself. I have a 75, 50, 29, and two turtle tanks, turtles being the the only ones I regularly change water. No deaths, plants are healthy(NO SUPPLEMENTS OR CO2 added), water is clear, and I’m using HOB filters with only ceramic balls. There’s guides for what you want online that will help far more than these comments.

**Q: Fluval fx4 or fluval 406? 80 gallon planted tank. what do you think?**
A: If you have a heavy stock of fish I would aim for 7-10x total gallons of filtration. 
Currently running 2 fx6 on my 260 gallon which is about 7x flow rate and I’m debating adding a third to get closer to that 10x mark.

These provide great bio filtration and if you set them up right with some tweaking can agitate the surface of the water which increases oxygen in the water and allows more life to exist in your aquarium.
