Fluval U2 Underwater Aquarium Filter 110 Litre (30 US Gal)

Product Information

Fluval internal filters are very easy to install and sit directly inside your fish tank, helping you save space and keep your aquarium clean and healthy.

It is designed with the latest technology that offers a 3-stage filtration, along with enough ventilation and increased water movement. The Fluval U2 Underwater Filter provides complete and efficient 3-stage filtration, including BioMax biological filtering, to create superior aquarium water quality. Unfortunately, deliveries to Northern Ireland, Republic of Ireland, Isle of Man, Isles of Scilly, Channel Islands, and certain Scottish offshore postcodes may not be possible. The Fluval U2 is can be used in aquariums between 45 and 110 litres, with a flow rate of 400 litres per hour.

The Adjustable 3-Way Flow Control feature (available in the Fluval U2, U3 and U4 models) lets you position the water flow output to meet your specific needs. To accelerate the test from a few months to a few days, I cleared out all my other external and internal filters and collected the dirt in a 10 l/2. The Top Output setting provides maximum circulation and oxygenation, the Integrated Spray Bar setting provides a gentle, even flow for planted aquariums, and the Bottom Output setting is for deep water agitation.

I contacted every manufacturer or supplier of internal filters I could think of and invited them to send in a filter for review.As well as being essential for health, Internal filters are great space savers for those with limited space around the aquarium, as they can simply sit inside it. The whole filter hinges forward for complete removal from the aquarium, leaving the fixing bracket in situ.

Not much really, other than the flip-top was a bit stiff on our new model and impeller access isn’t as accessible as it was on the previous Fluval plus model.
