External Aquarium Filter sera UVC-Xtreme 1200 with UVC sterilizer, external canister filter

sera UVC-Xtreme 1200 is an external canister filter with an integrated UVC sterilizer designed for mechanical and biological filtration as well as control of free-floating algae and microorganisms. Built for use with both freshwater and marine aquaria, this unit combines media-based filtration, powerful water circulation and UV treatment to improve water clarity and support stable tank conditions. The compact external canister design locates filtration equipment outside the display aquarium, allowing flexible media layering and straightforward maintenance.

Advantages

The integrated UVC sterilizer reduces suspended algae and certain microorganisms without chemical additives, while the canister layout enables efficient separation of mechanical and biological media. High flow capacity supports improved circulation and oxygen exchange, and the external placement minimizes visual and acoustic impact inside the aquarium. Components are designed for routine cleaning and media replacement, offering predictable performance for long-term aquarium operation.

Suitable for

• Freshwater community and planted aquaria
• Marine and reef tanks that need external filtration
• Aquaria requiring control of green water and suspended algae
• Systems where flexible filtration media arrangement is desired

Key specifications

• Filter type: external canister with built-in UVC sterilizer
• Filtration stages: mechanical and biological with media chambers for custom media
• Intended water types: freshwater and saltwater
• Functionality: water circulation, mechanical filtration, biological filtration, UV treatment for water clarification
• Installation: external placement with inlet and outlet hoses for aquarium connection

How to use

Position the canister below or beside the aquarium on a stable surface and connect inlet and outlet hoses according to the supplied instructions. Install appropriate filter media in the provided chambers to create a mechanical layer (sponges or floss) followed by biological media (ceramic rings, bio-balls or sintered media) and place the UVC lamp in its designated housing. Prime the unit and start the pump, checking for correct flow and absence of leaks. Monitor water clarity and replace or clean mechanical media regularly while maintaining biological media to preserve beneficial bacteria.

Usage recommendations

Use the UVC function selectively: operate the sterilizer for limited periods to control green water and pathogens, avoiding continuous long-term use to reduce impact on beneficial microorganisms. Match filter media selection and maintenance frequency to aquarium stocking levels and feeding rates to maintain stable biological filtration.
