Fluval U Range Internal Filters

Fluval U Range Internal Filters

Fluval® U Series internal Filters provide complete and efficient 3-stage filtration, including BIOMAX biological filtering (U2, U3 and U4 models), to create superior aquarium water quality. They provide the option of setting the flow output in 3 different positions. The Adjustable 3-Way Flow Control feature (U2, U3 and U4 models) lets you position the water flow output. The Top Output setting provides maximum circulation and oxygenation, the Spray Bar setting provides a gentle, even flow and the Bottom Output setting is for deep water agitation.

Fluval® U Filters also include a flip-top lid that allows easy access to the filter cartridge for maintenance or replacement including Fluval's Clean & Clear cartridge (HA499). Packed with special high performance resins, Clean & Clear is proven to reduce phosphate and nitrate while preventing the spread of algae, providing you with a cleaner, clearer aquarium and healthier fish for longer intervals.

In addition, Fluval® U Filters offer installation versatility: they can be installed vertically against the aquarium wall to create currents or customized flow patterns; or they can be placed horizontally in shallow water tanks or to create decorative features such as waterfalls. Offering outstanding 3-stage filtration, increased water movement and vital aeration, Fluval U-Series internal filters are the perfect solution where external filtration is not possible.
