Fluval U1 Underwater Filter – 55 L (15 US gal)
Fluval Nano Aquarium Filter is an optimal water filtration system for small aquariums up to 55 litres (15 US gal), including Fluval’s EBI Nano Shrimp Habitat and Fluval’s Flora Aquatic Plant Kit.
Equipped with foam filter media, it provides effective and thorough mechanical and biological filtration. A fine foam pad traps small debris and a Bio-Foam captures debris and houses nitrifying bacteria. The filter also provides the option of adding a carbon cartridge (sold separately) for additional chemical filtering.
The Nano Filter has an adjustable flow output with an attachable spray bar that distributes a gentle, even flow of water, making it safe for delicate fish or shrimp.

The U1 filter works well for my 10-gallon tank. Water clarity improved quickly, and the gentle flow is perfect for my shrimp. Easy to clean and maintain. I’ve used it for over six months with no issues.

Good filtration for a small tank. The spray bar helps distribute water evenly, which is great for sensitive fish. I added a carbon cartridge later for better water taste, but it wasn’t necessary at first.

I bought this for my nano shrimp tank. The filter runs quietly and keeps the water clean. The foam media traps debris well, and the bio-foam supports beneficial bacteria growth.
