The TUNZE® Comline® opens the way for compact aquarium components for internal operation, ultra functional, sophisticated, with clearly defined lines.
The Comline® is a multi-functional product line: Surface and substrate zone intake, high flow propeller pump filter, flash protein skimming, the system creates a natural environment in the aquarium with a compact footprint. The goal, more performance from less space. Comline® components meet these requirements and the visual harmony of the aquarium is maintained. It is no longer necessary to hide technical equipment in the aquarium; instead, it forms an integral part of it. The system is highly effective; all organic pollutants are removed from the environment directly, while the path the water has to cover is short and direct. The risk of leakage is almost zero. The highly efficient technology enables reduction of the volume of the internal equipment, as well as significantly reducing the energy consumption .

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 in.). 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 verfoaming 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.
