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: I would order again. - Great unit, works great. Easy install. Review: Looking for a canister filter? Look no further!!! - So, it's only day one of having my tank filled and filter running, but that's all I needed to have enough information to write an initial review. Why? Three reasons. I'll start with the easiest...as with my experience with the Fluval 306 in the past, the FX4 is extremely quiet, which is an absolute must!!! Second, the filter is extremely easy to set up. Finally, because I don't have any standard faucets where I can use a hose adapter, I tried a couple other ways to fill my tank...both of which failed. I finally decided I would just carry buckets of water over to the filter and try out the pump function of the FX4 and HOLY MOLY, what a life saver!!! Yes, with a 120 gallon tank, it took 20+ trips from my kitchen sink to the aquarium (I'm going to figure out a simpler plan for water changes that's for sure :) ), but the pump function work flawlessly and vwalla, tank filled! Fluval has never let me down. This is the third filter of theirs that I have used... I definitely recommend them to anyone trying to decide which one to use. ## Features - Multi-stage filter pumps out 700 US Gal (2,650 L) of water per hour, Smart Pump advanced microchip technology continuously monitors and optimizes pump performance - Self-starting – just add water, plug in and Smart Pump will take over, trapped air auto-evacuated every 12 hours to ensure maximum efficiency - Removable, stackable media baskets eliminate water bypass and hold a total of 1 US Gal (3.9 L) of media, all filter media included - mechanical, chemical and biological - Compact 16.5 in (42 cm) tall design - easily fits under most aquariums ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00N45GLZQ | | ASIN | B00N45GLZQ | | Best Sellers Rank | #6,420 in Pet Supplies ( See Top 100 in Pet Supplies ) #16 in Aquarium Filters | | Brand Name | Fluval | | Color | Black | | Customer Reviews | 4.4 4.4 out of 5 stars (2,455) | | Date First Available | July 17, 2016 | | Flow Rate | 2650 Liters Per Hour | | Global Trade Identification Number | 00015561102148 | | Included Components | Product in Descripton | | Is Discontinued By Manufacturer | No | | Item Dimensions L x W x H | 15.6"L x 15.6"W x 15.6"H | | Item Type Name | Fluval FX4 High Performance Canister Filter | | Item Weight | 6.43 Kilograms | | Item model number | A214 | | Manufacturer | Rolf C.

(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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I would order again. *by D***T on March 12, 2026* Great unit, works great.

I have experimented with many aspects of the hobby, studied everything, and done trail and error. Now I just run one 150 gallon tank, but at times have had many. I also have out door ponds. What I know is that most crap you read from so called experts on the web are "crap". After 50 years the basics are the same. The equipment has improved. Most people have no clue as to what a filter can do or should do. Go to my forum at yardcraphome dot com and open the critters section. I hooked this fx4 in today. I have been running the older fx5 (new model is fx6) for years and consider it a good buy. The fx5 had some challenges as to leaks and easy to break clamps, but suspect/hope they improved with the fx6/fx4 update. The fx5 is very good, best filter I have owned. Flow rate is important, but also is volume. These fx6/fx4 are huge. If you just want flow, buy a circulation pump. What you want is the water to pass over lots of helpful things before returning to the tank. I use multiple filters for different things as that helps as to maintenance. . One (fx5) is mainly for biological which is by far the most important. Due to the great 900 gal output, have it hooked to a a Tetra Pond bio filter that they claim handles 4000gal (doubt that). That reduces flow rate, but the combination is over kill for biological in my tank. The two together are like a large, but closed sump filter which can hold lots of bio material. The now dead Fluval 300 (or something?) was for chemical and needed replacement. I looked at filters to replace it and almost went with the new Ehiem 600 (great filters), but in the end got the small brother of the large Fluval that is still working great after years. I decided on the fx4 as opposed to the fx6 due to the fact the volume was enough when just for chemical, and I don't want my tank to become a rushing river. One thing with these is adjusting flow rate is very easy so maybe should have gone with the fx6. I hooked it up today and the only problem was a leak at the input connection. I wrapped some Teflon tape and easy fix. I filled it with Chemi-pure (because I have used it for decades) and and Purigen (which is just an excellent product). The flow rate is not that much more and my fish friends are large fish. I don't think flow reduction will be needed. My opinion is that for many, the fx4/fx6 is a best buy. The down side is they are large. Large is also the good part, but maintenance must be done from time to time so keep that in mind. These are heavy. I have a small room with a sink where filters live and tubes pass through the wall, so easy for me. My 3rd filter is the Fluval G6 which is a joke. This would be good for a nerd type with a small tank with low fish levels. I only keep it hooked in for the mechanical cartridge (no where near as good as the older Magnums, but very easy to service). Mechanical filtration occurs with all filters and while nice, should not be the focus of your filter choices. ## Frequently Bought Together - Fluval FX4 High Performance Canister Aquarium Filter - Multi-Stage Filtration, Built-In Powered Water Change System, and Basket-In-Basket Tray Design - Fluval FX Spray Bar Kit, Aquarium Filter Water Aeration Accessory - Fluval E 300 Watt Electronic Heater --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/16476086-fluval-fx4-high-performance-canister-aquarium-filter](https://www.desertcart.sc/products/16476086-fluval-fx4-high-performance-canister-aquarium-filter) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-05-05*
