The Comline® DOC Skimmer 9004 is designed for use in seawater mixed aquariums / soft coral aquariums up to 250 litres or sensitive reef biotopes with stony corals up to 150 litres. It works based on the TUNZE® Flash Skimming principle, water supply is provided via an efficient surface intake system with bacteria film removal. Thus, the system can also be used as a "standalone solution" in the aquarium. The featured TUNZE® Foamer generates many fine air bubbles with a diameter between 0.1 and 0.3mm, which ensures particularly quiet operation.
The Comline® DOC Skimmer is ready for installation, including Magnet Holder suitable for glass with a thickness of up to 12mm.

Immersion depth: approx. 225mm to 245mm
Skimmer cup volume: 200ml
Air output: approx. 150 litres per hour
Power consumption: 4W, 230V/50Hz

The Tunze "Flash skimming" principle enables highly efficient foam production.
Principle: Protein-rich surface water is mixed with water thoroughly in the TUNZE® Foamer. On the surface of the air bubbles forming, pollutants such as protein, cellulose, dead cells, etc. are adsorbed immediately, the air bubbles are very fine, with a diameter between 0.1 and 0.3mm. The water/air mixture is expanded and stabilized in the skimmer cup, the water returns to the aquarium, and the protein-loaded air bubbles reach the skimmer cup reactor. The patented anti-overfoaming system intermediate chamber with phase water prevents the skimmer from overfoaming and controls the skimmer performance, depending on the water level and organic load.
The particularly high efficiency of the "flash skimming" principle compared to large skimmers with long contact time is obtained because the substances adsorbed by the air bubbles are not released again, thus they don't return to the aquarium water again.
