The Comline DOC Skimmer 9004.001 is designed for use in seawater as well as mixed and soft coral aquariums up to 300 liters, or for sensitive reef biotopes with hard corals up to 150 liters.

The Comline DOC Skimmer 9004.001 is equipped with two Magnet Holders 6025.512 (1) with a holding force for glass thicknesses up to 12mm (3/8“). The small magnet is attached to the Comline, the large one is placed outside the aquarium.

The Comline DOC Skimmer 9004.001 is designed for use in seawater up to 300 liters. 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 0.1 to 0.3 mm (.0039 to .011 in.) and is especially quiet during the operation. The Comline DOC Skimmer with a magnet holder for glass up to a thickness of 12 mm (1/2”) 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 0.1 and .3mm.

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.
