The OASE EcoFlow 200 is the most powerful internal filter in the EcoFlow series and is designed for aquariums up to approximately 200 liters. It is suitable for medium-sized aquariums that require reliable filtration, good water circulation, and easy maintenance. The mechanical and biological filtration helps keep the water clear and contributes to stable conditions in the aquarium. The integrated spray bar ensures even movement of the water surface when needed, thereby supporting gas exchange. The included Venturi system allows additional oxygen to be introduced into the aquarium. The water flow rate can be individually adjusted at the outlet, while the adjustable flow direction enables targeted water distribution within the aquarium. The EcoFlow 200 demonstrates its particularly practical design during regular cleaning. The filter unit is held in place by integrated magnets and can be easily removed, while the pump unit remains in the aquarium. This keeps maintenance simple and quick
