The Comline® DOC Skimmer 9004 is an internal skimmer for mixed marine/soft coral aquariums up to 250 liters or for hard coral reef biotopes up to 150 liters. Based on the TUNZE® Flash Skimming principle, it draws water from the surface by removing the oily film, allowing it to operate in a standalone configuration. Its TUNZE® Foamer generates a large quantity of air bubbles with a diameter between 0.1 and 0.3 mm, operating exceptionally quietly.
The Comline® DOC Skimmer 9004 comes ready to use with a Magnet Holder for glass up to 12 mm thick; a second Magnet Holder can be added for thicker glass.

Recommended for marine aquariums from 60 to 250 litres depending on the organic load.
