Don't let your filtration create an eyesore in the middle of your beautiful aquascape. Tunze Comline filters deliver powerful, quiet internal filtration with minimal visibility.


Nano and all-in-one aquariums can present some unique challenges to providing effective mechanical filtration. Tunze has a long-standing reputation for producing the highest quality, best-performing internal filters on the market. For aquariums that don't come equipped with an overflow drain or that lack room for a filtration chamber, the Tunze Comline filters are the perfect choice.



  • Extremely compact & quiet
  • Rotating intake for versatile positioning
  • Versatile media chamber
  • Dual filter intakes
  • Surface skimming overflow
  • Pre-filter chamber for probes
  • Adjustable Comline energy-saving pump
  • Patented magnetic mount


The 3161 delivers compact, efficient filtration with a built-in surface skimmer, as well as other thoughtful touches like a small chamber for pH or temp probes. The Comline filters will efficiently remove surface scum, while the main chamber can accommodate filter floss or a small bag of chemical media such as activated carbon. The patented magenetic mounts will securely hold the filter on the side of the tank while the silicone rubber dampers prevent any vibration transfer to the glass, keeping noise to a minimum. Perhaps best of all, these filters are backed by Tunze's world-class support and a 24 month warranty.
