## Long description

The sera Fil Bioactive 250 external aquarium filter with integrated UV lamp is designed for small to medium freshwater and marine aquaria. It combines mechanical, biological and chemical filtration stages in a single unit and includes a UV lamp to clarify water and reduce free-floating microorganisms. The filter features multiple media compartments, adjustable flow control and an accessible design for routine maintenance, supporting stable water parameters and improved visual clarity.
