Comline® DOC Skimmer 9004

The Comline® DOC Skimmer 9004 is designed for use in seawater up to 250 liters (66 US gal.). It operates according to the TUNZE® flash skimming principle and acquires the water through an efficient surface suction with a surface film removal, and can therefore also be used as a “stand-alone” solution in the aquarium. The TUNZE® Foamer generates large volumes of fine air bubbles with a diameter of between .1 and .3 mm (.004″ – .012″) and is especially quiet during operation.
The Comline® DOC Skimmer with a magnet holder for glass up to a thickness of 12 mm (½”) is supplied installation-ready.

The flash skimming principle enables…

highly efficient foam production.
Organic-rich surface water is mixed thoroughly with small air bubbles in the TUNZE® Foamer. On the surface of the air bubbles, pollutants such as protein, cellulose, dead cells, etc. are adsorbed immediately, the air bubbles are very fine, with a diameter between .1 and .3 mm (.004″ – .012″). The water / air mixture expands and stabilizes in the skimmer cup reactor, the water returns to the aquarium, and the protein-loaded air bubbles spill over into the skimmer cup. The patented anti-overfoaming system intermediate chamber 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.
