## Long description

sera Serafil 120 is a compact internal aquarium filter designed for small freshwater tanks. Mounted inside the aquarium, it draws water through integrated filter media to provide mechanical and biological filtration. The unit helps reduce surface film, improves water clarity and contributes to a more stable aquatic environment for fish and aquatic plants in compact setups.
Advantages

How to use
Install the sera Serafil 120 submerged on the inner glass surface at a suitable height to ensure even water circulation. Connect to a compatible power source and position the outlet to achieve the desired flow pattern, avoiding direct strong currents on delicate plants or fish. Regularly inspect the unit and rinse the mechanical filter media in dechlorinated aquarium water during maintenance to avoid disturbing beneficial bacteria. Replace or refresh media according to observed performance and manufacturer guidance.
Usage recommendations
For optimal results, place the filter where it promotes gentle surface movement to reduce film and improve gas exchange without creating excessive flow. Perform routine maintenance at intervals based on tank stocking and bioload, and avoid cleaning all filter media at once to preserve biological filtration. Use in freshwater only and follow safety instructions for submerged electrical equipment.
