Internal aquarium filters – compact, efficient and easy filtration for your aquarium

An internal aquarium filter like the 4FISH 60i, 80i and 150i is a practical and space-saving solution for keeping your aquarium water clean and oxygenated. The filter is placed directly inside the aquarium, attached with suction cups to the inside of the glass, making it easy to install and remove for cleaning.

The filter combines both filtration and oxygenation in one unit, ensuring a healthy environment for fish and plants. The built-in filter sponge provides effective mechanical and biological filtration, while the energy-efficient motor with durable rotor ensures high performance with low noise levels.

With several models in the series, you can find a filter that suits both small and larger aquariums – from 350 liters per hour to a full 1200 liters per hour in water flow.
