The Tunze Comline® DOC Skimmer 9004 is designed for use in reef aquariums with soft coral aquariums up to 250 litres (66 USgal.) or in sensitive reef biotopes with stone corals up to 150 litres (40 USgal.). It works based on the TUNZE® Flash Skimming principle - water supply is provided via an efficient surface intake system with bacteria film removal. The Tunze Comline Doc 9004 can be used as a standalone solution in reef aquariums containing lots of live rock and is delivered with all of the accessories required for installation in an aquarium with glass no thicker than 12mm (a Magnet Holder is included).
• Surface intake for bacteria film removal
• Skimmer cup with a capacity of 200ml which also accommodates the foam reactor which is easy to remove
• Use of the Tunze Patented Magent Holder which can be used on glass aquariums up to 12mm thick
• Intermediate chamber with patented anti-overfoaming system
• Tunze Foamer with high air output and low energy consumption
• Bubble free outgoing water
• New Comline Design which is elegant and unobtrusive in the aquarium
• Air flow regulation and silencer for an exceptionally quiet operation
The “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.
