The trend within the nano aquaristics area is continuing. This type of tank is already often being offered with cabinet technology. If the question of the skimmer is addressed, you will find a multitude of models which are often too big, too expensive, or too inefficiently dimensioned. Thanks to the experience we’ve been able to gain in the field of motorized skimmers since 1963, we were able to develop the successful Comline®DOC Skimmer 9004 four years ago. The unit is highly compact with minimum space requirements, and it can operate efficiently in nano aquariums with up to 250 liters (66 USgal.). This model can also be used in cabinet filters with a variable level from 80 to 250 mm (3.1 to 9.8 in.) thanks to the specially designed container 9004.500. It is able to compensate water level fluctuations without the need for a constant adjustment, it contains a durable controllable Comline® pump and a post filter just like any DOC Skimmer cabinet. The Comline® DOC skimmer 9004 can function optimally in this 9004.500 container just like in any customized aquarium. Therefore, it offers the benefits of our larger models such as the easily removable cup, the Anti Over-foaming System and the Flash Skimming feature. The DOC Skimmer 9404 compact is very easy to install, features silicone feet for a completely silent operation and can be easily positioned in every nano cabinet filter. Acrylic container specifically adapted for the 9004, or for every customized device on the market. Base plate with silicone feet, no vibrations will be emitted in the filter. Comline® energy-saving pump 900, energy-efficient and adjustable from 250 l/h (66 USgal./h) up to 850 l/h (225 USgal./h). Removable post filter enables a perfect added mechanical filtration down to 300 µm using nylon fibers with only a minor biological action. This ensures that no unwanted nutrient and nitrate deposits can develop in case of longer cleaning intervals. The filter can be filled with other filter media, such as activated carbon or phosphate absorbers.
