Everything about internal aquarium filters in the aquarium shop


An internal filter is the centrepiece of every aquarium - it ensures clear, clean water and a healthy environment for your fish and plants. In contrast to external filters, the internal filter is placed directly in the aquarium and cleans the water where it is needed most.


What is an internal filter?

An internal aquarium filter consists of a pump and various filter materials that work mechanically and biologically. Suspended matter, food residues and other impurities are reliably removed, while beneficial bacteria in the filter material break down pollutants. This keeps the water clear, odour-free and the water values stable - the best basis for healthy fish and vital plants.


Advantages of an internal filter

  • Compact design - ideal for small to medium-sized aquariums
  • Easy installation and cleaning
  • Quiet operation
  • Effective filtration and oxygen enrichment
  • Safe to use even in tanks with young fish or shrimps
