Why choose an external aquarium filter?

External aquarium filters, also known as external filters, offer several advantages over internal filters:

  • Larger filter capacity: external filters have more space for filter media, which ensures better mechanical, biological and chemical filtration.
    Improved water quality: due to the larger filter surface, external filters can remove more dirt and waste, resulting in clearer and healthier water for your fish and plants.
  • Space-saving: they are placed outside the aquarium, leaving more space in the aquarium for decoration and fish.
  • Easy maintenance: modern external filters, such as the Oase BioMaster series, are equipped with convenient maintenance features such as the EasyClean pre-filter module.

What should you pay attention to when purchasing an external filter?

It is important to consider a few factors before purchasing an aquarium filter.

  • Capacity: choose a filter that is suitable for the water volume of your aquarium. Check the maximum capacity that the filter can handle to ensure optimal performance.
  • Pump speed: The flow should be strong enough to filter the water well, but not so strong that it disturbs the fish.
  • Filter media: Look at the available filter materials and their specific functions for biological, mechanical and chemical filtration.
  • Energy consumption: Choose an energy-efficient model to save costs and contribute sustainably to the environment.

Maintenance and tips for long-lasting performance

To maximize the lifespan of your external filter, regular maintenance is crucial:

  • Cleaning: Clean the pre-filter module regularly to prevent blockages. In addition, make sure that the hoses and connections are free of algae and dirt.
  • Check and replace: Check and replace filter media according to the manufacturer's recommendations.
