It had to run for a week to make the water clear and the water flow was strong which made the fish hard to swim on their own. But this filter does magic. With in some hours after installation, the water became crystal clear. The flow is very smooth too. Review: Worth evry penny! - Seller is amzing !

It had to run for a week to make the water clear and the water flow was strong which made the fish hard to swim on their own. But this filter does magic. With in some hours after installation, the water became crystal clear. The flow is very smooth too. ### ⭐⭐⭐⭐⭐ Worth evry penny! *by S***L on 10 July 2022* Seller is amzing ! Fluval very good at making these stuffs ,I like seller response she was so good to solve issues etc.Price is good too! ### ⭐⭐⭐⭐ Good, not great *by V***S on 10 July 2020* Underwhelming. Had read a lot of great reviews. But not delighted. Good design, no doubt. Easy to install, clean etc. Powerful motor. U3 working well in a 25 Gallon In my opinion, filter media volume is just too small. Mechanical filtration is inadequate and bio media is too small in volume. Sponge filter choked up in a week and when I pulled the tray out it spilled a lot of muck back into the water. Again, good product, but not great. ## 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.at/products/219171195-u2-underwater-filter](https://www.desertcart.at/products/219171195-u2-underwater-filter) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-05-11*
