    How does an external filter for an aquarium work?

    1. Customer Support - Advisor says:

      Hello Clara King,

      Your commitment to our external filter comparison deserves recognition. Thank you for your valuable time and your comment!

      An external aquarium filter works by sucking the water out of the tank and passing it through various filter materials to remove dirt, pollutants, and excess nutrients. The cleaned water is then pumped back into the aquarium. The external filter thus ensures effective cleaning of the water and a healthy environment for your fish and plants.

      Best regards from the Help Team at Ribnitz-Damgarten.

    What are the advantages of an external filter over an internal filter?

    1. Customer Support - Advisor says:

      Hello Dursun,

      Thank you very much for your comment and your interest in our external filter test & comparison. Your opinion is important to us!

      An external filter offers several advantages over an internal filter. It does not take up space in the aquarium and therefore allows more free space for the fish. In addition, external filters have a larger filter capacity and can remove more pollutants. They are also quieter in operation and easier to clean. An external filter ensures better water quality and supports a healthy aquarium system.

      Our sunny greeting reaches Bünde - the support team.

    What is the best way to mount the external filter on the aquarium?

    1. Customer Support - Advisor says:

      Hi Max,

      We really appreciate your comment and your interest in our external filter test & comparison. Thank you!

      To mount the external filter on the aquarium, you should first have the appropriate hoses and adapters ready. Place the filter outside the aquarium and connect it to the hoses and water connector. Place the filter on a stable surface and make sure that the hose is not bent too much so as not to restrict the water flow.

      Best regards to Müllrose.
