The Comline DOC Skimmer 9004 is designed for use in seawater up to 250 litres. It is based on the TUNZE Flash Skimming principle and obtains the water from efficient surface suction with crimping skin removal and can therefore also be used as a stand-alone solution in the aquarium. The TUNZE Foamer generates a large amount of fine air bubbles with a diameter between 0.1 and 0.3 mm, it is particularly quiet during operation. The Comline DOC skimmer is ready to install with magnetic holder up to 12 mm glass thicknesses. Surface extraction with crimping skin removal. Foam pot with 0.2 litre capacity also contains the foam reactor, easy to remove. Attachment with patented magnetic holder up to 12 mm glass thickness. Intermediate chamber with patented anti-overfoaming system. TUNZE Foamer 9004.040, high air output and low energy consumption. Bubble-free output water. Comline design: practical to use, elegant and discreet in the aquarium. Air regulation and silencer for a particularly quiet running. The flash skimming principle ensures efficient foam production with high efficiency. Principle: the protein-rich surface water is mixed very intensively with air in the TUNZE Foamer. In the formation of air bubbles, waste materials such as protein, cellulose, dead cells, etc. are immediately absorbed on their surface, there are very fine air bubbles with a diameter between 0.1 and 0.3 mm. The mixture of water and air bubbles is expanded and stabilised in the skimmer body, the water returns to the aquarium and the protein-charged air bubbles into the reactor of the foam pot. The patented anti-overfoaming system intermediate chamber with phase water prevents the skimmer boiling over and regulates the foaming performance depending on the water level and organic load. The flash skimming principle achieves the particularly strong efficiency compared to skimmers with high construction and long contact time, thanks to the fact that adsorbed substances are not torn off by the air bubbles and return to aquarium water. Each saltwater aquarium has a different sensitivity in terms of organic stress thanks to its biotop collection. Starting from a standard saltwater aquarium with soft corals, the information about the appropriate aquarium size may vary in other biotop combinations. Therefore, for sensitive biotopes, the aquarium volume recommended for the skimmer should be reduced. with a tee. Low sensitivity, no shot. For soft coral aquariums, e.g. with long-polypious corals and anemones, the proportion of dissolved organic substances can be higher, sometimes they are even vital. The DOC skimmer can be used for the recommended aquarium volume without a shot. Medium sensitivity, 40% offset. A medium organic sensitivity usually have mixed basins of soft and stone corals (LPS). There are often filterers, sponges, etc. With these aquariums, with a tee of approx. 40% of the specified foaming performance. A DOC skimmer for 1,000 litres should therefore be maximum for an approx. 600 litre basin. High sensitivity, 60% kill aquariums with predominantly small polypy stone corals (SPS) require a particularly high degree of purity. They should not have any significant strain on phosphate or nitrate. Good oxygen saturation and very clear water are a prerequisite. The DOC skimmer is often also used in these aquariums as a "stand-alone solution", so a model for 1,000 litres should be maximum for approx. 400 litre basin. High sensitivity and high load, 70% shot rock coral aquariums with high fish stock require an extremely large skimming performance. The skimmer must ensure the purity level for stone corals with above-average fish load, as a "stand-alone solution" a special high performance is expected. A DOC skimmer for 1,000 litres should therefore be maximum for an approx. 300 litre basin. These devices work according to the horizontal rotation principle, the whole skimmer works with the so-called contact foaming, so coarser particles in plankton size are not absorbed. This operation is very gentle, the extremely flat design makes it the smallest skimmers in its performance class. Low sensitivity, no breakdown. For soft coral aquariums, e.g. with leather soft corals and anemones, the proportion of dissolved organic substances can be higher, sometimes they are even vital. This aquarium type can use the recommended aquarium volume without a knot. High sensitivity for breeding pools with plankton, 70% off stone coral aquariums or even breeding pools with plankton food require a particularly high degree of purity. Good oxygen saturation and clean water are a prerequisite. A classic DOC skimmer for 1,000 litres should therefore maximum for an approx. 300 litre basin.
