Comline ® DOC Skimmer 9004 is an internal skimmer for marine aquariums up to 250 liters. It is based on the TUNZE ® “Flash skimming” principle and draws its water from surface suction by eliminating the greasy film. This advantage allows it to operate in the aquarium in a “stand alone” version. Its TUNZE ® Foamer generates a large quantity of air bubbles with a diameter between 0.1 and 0.3 mm with particularly quiet operation.
The Comline ® DOC Skimmer 9004 is delivered ready to use with Magnet Holder up to 12 mm glass thickness.
Flash Skimming
The “Flash Skimming” principle guarantees efficient foam production with high performance.
Principle: Surface water with a high protein content is intensely mixed with air by the Foamer TUNZE®. The different substances to be extracted such as proteins, cellulose, dead cells, etc. immediately agglomerate on the surface of these fine bubbles with a diameter between 0.1 and 0.3 mm. The mixture of water and air bubbles is then relaxed and stabilized in the body of the skimmer, the treated water returns to the aquarium and the air bubbles loaded with the various materials are pushed towards the evacuation cup . The patented principle of the Anti Overfoaming System chamber with its process water prevents runaway of the skimmer and regulates its performance according to the water level and the organic load. Compared to devices of higher construction or having a longer contact time, the skimmer with the “Flash Skimming” principle achieves high skimming yields and avoids the phenomena of protein releases. Substances stuck to the air bubbles are not separated or drawn back into the aquarium water.
Skimming cup with a capacity of 0.2 liters
also incorporates the reactor, easy to extract.
