The large Comline® DOC Skimmer 9012 is designed for use in mixed seawater aquariums/soft coral aquariums from 200 to 1200 liters (53 to 317 USgal.), or for sensitive reef biotopes with hard corals up to 500 liters (132 USgal.). 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 between 0.1 and
0.3mm (.0039 to .011“) and is especially quiet during the operation. Silicone buffers on the skimmer prevent the transfer of vibrations to the aquarium glass pane. The Comline® DOC Skimmer with a Magnet Holder for glass up to a thickness of 15mm (1/2”) is delivered installation-ready.

Features:
-The skimmer cup with a capacity of 0.7L (0.18 USgal.) also contains the foam reactor, which can be easily removed.
-Surface suction with surface film removal.
-Air flow regulation and silencer for an exceptionally quiet operation
-Intermediate chamber with a patented antioverfoaming system.
-Silicone buffers on the skimmer prevent the transfer of vibrations to the aquarium glass pane.
-TUNZE® Foamer 9012.040, high air flow performance and low energy consumption.
-Bubble-free outgoing water.
-Attachment with a patented Magnet Holder for a glass thickness of up to 15mm (1/2“).

The Tunze Comline DOC skimmer utilizes Tunze's "Flash Skimming" principle. The skimmer is quiet and generates a very large volume of small bubbles for efficient skimmer operation. It operates stand-alone without needing any additional equipment (feed pumps, etc) and mounts to the tank via a convenient magnet holder strong enough for glass up to 1/2" thick.

The TUNZE® Foamer generates large volumes of fine air bubbles with a diameter of .0039 to .011 in. (0.1 to 0.3 mm) On the surface of the air bubbles, pollutants such as protein, cellulose, dead cells, etc. are adsorbed immediately. 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 over foaming and controls the skimmer performance, depending on the water level and organic load. This “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.
