Review: Quiet, powerful, and a great upgrade for small to medium tanks - I recently upgraded to the Fluval U2 Underwater Filter after using the standard filter that came with my Pets at Home LoveFish tank, and the difference is huge. The old filter felt like a gentle trickle in comparison. This one actually moves the water properly and keeps it clean and clear. The Fluval has three flow settings depending on what you need, top, bottom, or full middle. I personally use the top outlet with the nozzle angled towards the surface. This keeps the surface water moving and means I no longer need to run a separate air pump. There’s less tubing in the tank, far less noise, and lower power use overall. I’ve been running it for about a month now with no issues at all. It’s easy to maintain, runs quietly, and feels well made. I’m using it in a 64L tank with shrimp, tetras, and snails, and the flow is just right, strong enough for good circulation but gentle enough for smaller fish and shrimp. I got it for £40.50 it’s great value for what you get, especially compared to the basic filters that come with starter tanks. If you’re still using one of those, this is a solid upgrade that makes a big difference to water clarity and general tank health. Review: Perfect for around 15 gallons - I purchased this filter for an tropical aquarium with a 14/15 gallon capacity. The dimensions of the aquarium is (h)30cm x (d)30cm x (w)60cm. I find that this filter is the perfect size for the aquarium with a strong flow that can be slowed down and enough filtering gallon per hour to deal with the waste in the aquarium. In this tank I have: - x1 platy (male) - x1 sword tail (male) - x1 betta (female) - x2 albino corydora - x5 neon tetra - 6 Assassin snails - Plants - A few desertcart sword - Floating Water wisteria - Quite a lot of Java fern on bog wood - About 1/6th of the aquarium has guppy grass covering the area - 3 Marimo moss balls I find that with this set up I only need to do a 25% water change every 1 and a half weeks or longer and I still have water that is clear and to the correct parameters. The flow can be changed into five or more different directions depending on how you think about it and also features a venturi pipe to pull air bubbles into the water I find I have the flow on the top outlet pointing downwards towards the bottom of the tank with the venturi pipe working. This provides the surface agitation needed for aerated water and the surface free from too much food debris. The whole unit is removable from the working pump to be able to clean the impeller which is essential. Offering 3 different filter types this is one of the best in-tank filters on the market. the pump pulls water down through two sponges on each side of the filter, through filter floss and filter carbon then through ceramic biological filtration and out. To clean the filter media the filter then leans forward off of the tank wall and you can remove the sponges in their plastic holders from the top. Pros - Venturi - Nice looking - 3 stage filtration - Gph - Fluval good brand - Different angle and direction outlet Cons - Can not have flow from more than one of the different options unless you modify it with a drill - Flow could be too much for a male betta but the three centre settings should be slow enough Notes - I was originally going to get the u3 for the tank but it proved too big. This size really is the best internal filter you can get for its size. ## Features - Warning:Not suitable for children under 3 years. For use under adult supervision - Top Access - for easy maintenance - Adjustable flow control - 3 Stage Filtration ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001Q1HPGE | | Best Sellers Rank | 2,406 in Pet Supplies ( See Top 100 in Pet Supplies ) 2 in Aquarium Filters | | Brand | Fluval | | Capacity | 110 litres | | Container Type | Aquarium | | Country Of Origin | United Kingdom | | Customer Reviews | 4.1 out of 5 stars 8,145 Reviews | | Global Trade Identification Number | 00015561104708 | | Included Components | Filter | | Included components | Filter | | Installation Type | Freestanding | | Item Dimensions L x W x H | 25.4L x 10.2W x 12.7H centimetres | | Item Type Name | HAGEN FLUVAL U2 UNDERWATER FILTER | | Item Weight | 0.64 Kilograms | | Manufacturer | KOMQI | | Manufacturer Part Number | HGA470 | | Material | Plastic | | Material Type | Plastic | | Maximum Flow Rate | 400 Litres Per Hour | | Model Name | HAGEN FLUVAL U2 UNDERWATER FILTER | | Model Number | A470 | | Number of Items | 1 | | Number of Packs | 1 | | Other Special Features of the Product | Top Access, 3 Stage Filtration, Adjustable flow control | | Power Source | Corded Electric | | Product dimensions | 25.4L x 10.2W x 12.7H centimetres | | Purification Method | 3 Stage Filtration, Biomax | | Special feature | Top Access, 3 Stage Filtration, Adjustable flow control | | Supported Water TDS Level Maximum (PPM) | 300 | | UPC | 015561104708 | | Unit Count | 1 count | ## Product Details - **Brand:** Fluval - **Capacity:** 110 litres - **Included components:** Filter - **Installation type:** Freestanding - **Material:** Plastic - **Package information:** Aquarium - **Power source:** Corded Electric - **Product dimensions:** 25.4L x 10.2W x 12.7H centimetres - **Purification method:** 3 Stage Filtration, Biomax - **Special feature:** Top Access, 3 Stage Filtration, Adjustable flow control ## Images ![Fluval U2 Internal Aquarium Filter – Up to 110 Litre Fish Tanks, 400 L/H Adjustable Flow, 3-Stage Filtration with BioMax, Freshwater, Marine & Reptile Use - Image 1](https://m.media-amazon.com/images/I/61gX9DTvyjL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Does the whole unit go under water? No spray bar to make a noise? All the aeration underwater bubbles? My filter at the moment very noisy!** A: its very quiet, just a small hum if you get near it. It has 3 settings, one makes bubbles, the other ones are silent, you dont have to have the bubbles if the unit is under water, mine is just above the surface, i dont like to trail the wire in the water but some people do and the unit can sit in the bottom of the tank, it is large but a few plants will cover it, hope this helps **Q: Hi does the filer come ready to use or do I have to buy the filters and foam seperately?** A: Hi Leigh.It comes with the filters and biomax filter media :-) I get my refills from Amazon seller The Aquahut for £11.59 for a 2 pack foam pad, 2 pack cartridge pack and 170g box of biomax. Good value and very reliable seller. Have used them ever since I purchased my Fluval U2. Happy to help :-) **Q: I have lost the grey stopper that regulate the slow from the top filter. Is it possible to purchase these separately please?** A: You can use a blob of bluetac and vary the air flow like that. **Q: Will this filter work if I use it horizontally on its side, rather than vertically? I want to use it in my turtle tank which has a low water level** A: I can’t see it being a problem. How deep is your water though? This is enough filtration for a 110l tank so if you’ve only got a bit of water in the bottom a sponge filter may be a better option? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quiet, powerful, and a great upgrade for small to medium tanks *by D***N on 2 November 2025* I recently upgraded to the Fluval U2 Underwater Filter after using the standard filter that came with my Pets at Home LoveFish tank, and the difference is huge.

This size really is the best internal filter you can get for its size. ### ⭐⭐⭐⭐ A good, steady filtration system *by B***R on 3 December 2012* As someone who has owned fishtanks (tropical and marine) for most of their adult life, I have tried and tested many types of filters, from the old "undergravel" pump powered systems to the more common external filters. This purchase was to replace an external filter in my 180l tropical setup. I have finally given up on external filters. For their supposed benefits (less clutter in the tank, easier access for servicing etc) I have personally found them unreliable and when they go wrong they really do go wrong (airlock problems and pipe issues) I chose this item due to it being relatively compact, being a brand in the fish world, and its additional water circulation features. The beauty of an internal filter is in the setup - 10 minutes from reading the instructions through to it being operational and with minimal disruption to the fish. The unit looks okay - it is not too intrusive, but it is the water/air circulation which sets it apart from cheaper alternatives. The filter compartments are easy to access for cleaning. It is also very quiet running. Even after a few weeks of it being operational the water flow through the unit is still strong. Overall it is a good unit. The negatives. The actual filter media is very bespoke to the Unit. Personally I have always preferred being able to substitute manufacturers expensive filter media with cheaper options, the compact nature of this unit makes that difficult - so that is of course an additional expense in running this filter. But for a beginner, or indeed someone like me who has had enough of external filters leaking or not operating correctly, this provides a simple alternative at a decent price. ## Frequently Bought Together - Hagen Fluval U2 Underwater Filter - Fluval U2 Poly-Carb Cartridge, Replacement Underwater Aquarium Filter Media, 2-Pack, A490 - Fluval U Underwater Filter BioMax --- ## 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.com.pa/products/48327966-fluval-u2-internal-aquarium-filter-up-to-110-litre-fish](https://www.desertcart.com.pa/products/48327966-fluval-u2-internal-aquarium-filter-up-to-110-litre-fish) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-11-05*
