Tunze Comline® DOC Skimmer 9012 DC

Powerful internal protein skimming for demanding marine aquariums

The Tunze Comline® DOC Skimmer 9012 DC is a premium internal protein skimmer for reef and marine aquariums where quiet operation, compact design, and reliable nutrient export matter. Designed for in-tank use, it combines efficient surface intake, strong air performance, and DC controllability in one clean, space-saving unit. It is especially well suited for aquarists who want strong skimming performance without moving to a larger external or sump-based setup.

Excellent performance with low energy consumption

One of the biggest advantages of the 9012 DC is its balance between skimming power and efficiency. It delivers approximately 400 l/h of air capacity while consuming only about 9 W at 12V, helping reduce power usage without sacrificing serious marine filtration performance. Electronic speed control also allows quieter operation and more flexible adjustment to suit different aquarium conditions.

Ideal for mixed reefs, soft corals, and selected SPS systems

This skimmer fits a wide range of saltwater aquariums depending on nutrient load and stocking density. It is positioned for roughly 300 to 1,000 liters depending on tank load, and is also described for mixed seawater or soft coral aquariums from 200 to 1,200 liters, with sensitive hard coral reef systems up to 500 liters. That makes the 9012 DC a strong option for aquarists who want a compact skimmer with enough flexibility for both moderate and more demanding reef setups.

Surface film removal and efficient flash skimming

The Tunze Comline® DOC Skimmer 9012 DC uses a flash skimming design with effective surface suction, which helps remove organic waste directly from the protein-rich surface layer of the water. This supports cleaner water, improved gas exchange, and more stable overall aquarium conditions. Because it draws from the surface and can function as a stand-alone in-aquarium solution, it is especially attractive for marine aquariums where sump space is limited or a compact internal solution is preferred.

Quiet operation and compact installation

For many reef keepers, noise level is just as important as raw performance. The 9012 DC is built for quiet running, with fine bubble production, vibration-reducing silicone buffers, and a compact body that integrates neatly into the aquarium. The skimmer measures 140 x 110 x 415 mm, works at an immersion depth of approximately 255 to 285 mm, includes a 0.7-liter skimmer cup, and comes ready to install with a magnet holder for glass up to 15 mm thick.

A smart choice for modern reef aquariums

If you are looking for a compact but capable skimmer for a marine aquarium, the Tunze Comline® DOC Skimmer 9012 DC is an excellent choice. It combines strong skimming performance, low energy consumption, DC adjustability, surface film removal, and quiet everyday operation in a format that fits directly inside the aquarium. For reef keepers who want dependable nutrient control in a clean and efficient design, this is a very attractive solution.
