Three stage filtration with biomax for superior aquarium water quality, flip top access for quick and easy cartridge replacement, and three way flow control make the new fluval u series the benchmark in underwater filtration. Stage 1 foam removes large particles. In stage 2, the poly/carbon cartridge traps fine debris, improves water clarity and removes impurities.

Review: Acquistato in sostituzione del filtro integrato del mio Askoll Pure XL 94 litri. Con i pesci Oranda, che sporcano moltissimo, il filtro integrato nel coperchio non era sufficiente a garantire una buona filtrazione. L’acqua era sempre torbida e piena di impurità. In più il precedente, essendo integrato nel coperchio di plastica, era estremamente rumoroso. Questo Fluval è incredibile. Estremamente silenzioso, arriva completo di tutti materiali filtranti, ha l’uscita del flusso regolabile: - uscita dal basso - uscita centrale più distribuita - uscita dall’alto con valvola Venturi per l’ossigenazione (più rumorosa per via delle bollicine) Tutti i problemi di sporcizia nell’acqua si sono risolti nel giro di due giorni. In più la manutenzione sembra semplicissima in quanto il filtro è apribile dall’alto e i materiali sono facilmente estraibili. Consiglio a chiunque cerchi un filtro estremamente silenzioso ed efficace con un’ottima portata d’acqua senza necessariamente creare troppe correnti. Prezzo più che adeguato. Review: Just got this filter yesterday so cant say anything about longevity however so far so good! Please follow instructions carefully, I didnt remove the fan and run it under water which caused the fan to not work at first, however once I did that the filter worked great. I bought the filter for my turtle tank as a backup to my canister filter and it works great and turtle doesnt mind it. Also very quiet so far and very powerful! ## Features - Use as a primary filter for smaller aquariums, or supplementary filter for larger aquariums - Sleek design with easy grip water control panel and redesigned media cartridge to trap more debris - Convenient flip-top lid allows for quick and easy access to filter cartridge for maintenance or replacement - Position horizontally for shallow tanks, larger tanks with low water levels, or to create a decorative waterfall feature or vertically against aquarium wall to create currents or customized flow patterns - Designed for freshwater, saltwater and reptile environments up to 65 gallons ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001XRXY1G | | Best Sellers Rank | #14,034 in Pet Supplies ( See Top 100 in Pet Supplies ) #758 in Aquarium Accessories | | Brand Name | Fluval | | Capacity | 240 Liters | | Container Type | Filtration container | | Customer Reviews | 4.3 4.3 out of 5 stars (3,138) | | Global Trade Identification Number | 00015561104807 | | Included Components | Filter | | Installation Type | Freestanding | | Item Type Name | HAGEN FLUVAL U4 UNDERWATER FILTER | | Item Weight | 1.12 Kilograms | | Manufacturer | Rolf C.

Does this sit on the bottom where it could suck in the food and waste that collects on the bottom where my river rocks are? It has proven hard to get that out and the pleccu is not cleaning it up as of now.** A: Mine is laying on the bottom of my tank and i have never had it sitting upright. I can tell you it does pretty well sucking everything up. However, i usually have one spot in the tank, right underneath the filter where debris sits. When I need to water change I just make sure I get the debris out with a fish net. That seems to work pretty well. It is the best filter I have had so far (with a turtle that has killed 4 filters), just make sure to clean the motor fan with every water change or filter media change. **Q: Does the U4 filter have space to add activated carbon pellets?** A: Yes it can, in the center of the filter there a removeable plastic cage. I put a small Chemi Pure bag in it. But I didn't care for this filter and not cause it didn't work. But I was wanting something more as a skimmer type filter and I wasn't getting enough flow out this filter unit. But it did work, if your running this on a smaller tank say no 30 gal freshwater ok. I was running it on a 29 gal reef tank with lots of live rock and it couldn't push enough water around it. But it did filter the water good. **Q: Do all 3 outputs work at the same time?** A: No, you have to pick a setting. I use mine for moving water in the bottom of my tank. It also seems to be he strongest setting out of the 3 choices **Q: Can I change the direction of the water coming out of the nozzles? For example directing it upwards instead of horizontal.** A: There's a small directional piece on the end of each nozzle you can turn to minimally direct the flow - but not nearly that much. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***O on 23 February 2026* Acquistato in sostituzione del filtro integrato del mio Askoll Pure XL 94 litri.

Bought as original tank filter went down in my 130l , the pros of this filter are - -super quite , hardly any noise -smart looking / blends in / fits nicely -3 different spray modes (top , bottom or middle for gentle flow) So easy to use / setup and for maintenance The water is really really clear with the active carbon in the filter , it comes with ceramic media too which is a bonus Overall really good filter , highly recommend this in tank instead of external canister ## Frequently Bought Together - Fluval U4 Underwater Filter, Freshwater and Saltwater Aquarium Filter, A480,Black - Fluval U4 Bio-Foam Pad, Replacement Underwater Aquarium Filter Media, A488 - 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.tn/products/254683861-u4-underwater-filter-freshwater-and-saltwater-aquarium-filter-a480-black](https://www.desertcart.tn/products/254683861-u4-underwater-filter-freshwater-and-saltwater-aquarium-filter-a480-black) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-19*
