External aquarium filter sera UVC-Xtreme 800

The sera UVC-Xtreme 800 external aquarium filter is a canister-style filtration unit designed for freshwater and saltwater aquaria. It combines mechanical and biological filter stages with an integrated UVC sterilizer to support water clarity and reduce free-floating microorganisms. Installed outside the aquarium, the unit circulates water through multi-stage media to capture debris, promote beneficial bacterial colonization, and treat planktonic algae and pathogens with UVC exposure.

Advantages

The sera UVC-Xtreme 800 integrates mechanical filtration with biological media and an internal UVC lamp in a compact canister that operates quietly and offers adjustable flow. Its external setup preserves aquarium space and simplifies media replacement and maintenance. The combined approach addresses particulate removal, biological nitrification, and reduction of free-floating microorganisms, which helps maintain clearer water and a more stable environment for aquatic animals.

Suitable for

• Home freshwater aquaria with moderate to heavy stocking
• Planted tanks where water clarity and low pathogen load are important
• Office aquaria and display tanks requiring reliable external filtration
• Marine aquaria when used with appropriate media and maintenance

Key specifications

• Canister-style external filter with integrated UVC sterilization
• Combined mechanical and biological filtration stages
• Adjustable flow suitable for a range of aquarium sizes
• Quiet operation with external installation to save tank space
• Accessible media compartments for easy replacement and cleaning

How to use

Position the sera UVC-Xtreme 800 on a stable surface below or beside the aquarium and connect inlet and outlet hoses according to the supplied instructions. Prime the canister following the manufacturer’s procedure before starting the pump. Load recommended filter media in the correct order to ensure mechanical pre-filtration before biological media. Run the unit continuously to maintain circulation; monitor flow and water parameters regularly and replace the UVC lamp and filter media according to usage and lamp life guidelines.

Usage recommendations

Perform routine inspection and maintenance: clean pre-filter pads and hoses monthly or as needed, replace biological media on a staggered schedule to preserve beneficial bacteria, and replace the UVC lamp at manufacturer-recommended intervals. Match flow rate and media selection to aquarium size and bioload, and avoid exposing the unit to prolonged direct sunlight or freezing temperatures.
