Filter Technic > Internal Filters

Internal filters are the perfect choice when you need a space-saving, durable and particularly safe filtration system. Because they operate entirely inside the aquarium, there is no risk of leaks or water escaping, making them especially suitable for living rooms, offices and rental homes. Internal filters combine mechanical and biological filtration to ensure clear water and stable parameters.

Our range includes compact sponge filters, powerful multi-chamber systems, models with integrated surface skimmers and modular internal filters that can be adapted to individual needs. Many offer adjustable flow, energy-efficient pumps and very quiet operation, making them a great fit for noise-sensitive environments.

Thanks to their simple design, internal filters require very little maintenance: sponges, cartridges or biological media can be cleaned or replaced quickly without dismantling the entire unit. Their ease of use makes them excellent for beginners, while experienced aquarists appreciate their high level of operational safety and versatility.

Whether for freshwater tanks, aquascapes or shrimp setups, Aquaristikshop offers a wide selection of high-quality internal filters as well as matching spare parts and filter media for long-term, safe and efficient filtration.
