Technical Specifications

How to choose the right DOC skimmer for a saltwater aquarium?

Each marine aquarium, due to its individually created biotope, has different sensitivity to the load of organic compounds. The assumptions regarding the tank size are for the average soft coral marine aquarium, so these recommendations may vary depending on the biotope composition. Therefore, for sensitive biotopes, when choosing a skimmer, the recommended volume should be reduced or adjusted if necessary.

Low sensitivity, no adjustment

In aquariums containing soft corals, such as long polyps and anemones, the amount of dissolved organic compounds can be higher and sometimes even essential for life. 
The DOC skimmer for this aquarium volume can be used without needing an adjustment. 

Medium sensitivity, 40% reduction

In mixed tanks containing both soft and hard corals (LPS), a medium sensitivity to changing organic conditions is generally observed. Zooplankton, sponges, etc., are also often found in these aquariums. For these aquariums, a correction of about 40% of the indicated skimmer capacity is calculated. 
A DOC skimmer up to 1000 liters should be used for a tank with a maximum volume of approximately 600 liters. 

High sensitivity, 60% reduction

SPS-dominated stone aquariums require a particularly high degree of water purity. They should not be loaded with phosphate or nitrate. High oxygen saturation and clear water are essential. The DOC Skimmer is often used in these aquariums as a "standalone" solution. 
A DOC skimmer up to 1000 liters should be used for a tank with a volume of approximately 400 liters. 

High sensitivity and high load, 70% reduction

Aquariums containing hard corals and many fish require a very high skimmer capacity. A skimmer must provide a high degree of water purity for stone corals with a relatively large number of fish. When used as a "standalone" skimmer, the skimmer must be particularly efficient.
A DOC skimmer up to 1000 liters should be used for a tank with a volume of approximately 300 liters. 

In plankton breeding tanks 70% reduction

Hard corals or plankton breeding tanks for feeding require a particularly high degree of water purity. High oxygen saturation and clean water are essential. 
A DOC skimmer up to 1200 liters should be used in a tank with a volume of approximately 360 liters.

The TUNZE® Comline®

means compact aquarium components for internal operation, ultra-functional, sophisticated, with clearly defined lines.
The Comline® is a range of multifunctional products: 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 is more performance with less space. The Comline® components meet these requirements and the visual harmony of the aquarium is maintained. It is no longer necessary to hide the technical equipment in the aquarium; on the contrary, it becomes an integral part of it. The system is very efficient; all organic pollutants are removed directly from the environment, while the path the water has to travel is short and direct. The risk of leakage is almost zero. The highly efficient technology reduces the internal equipment volume and significantly reduces energy consumption.

Comline® DOC Skimmer 9001

Simple, quiet, and efficient, these are the requirements of today's aquarium components. These are the characteristics of the small Comline® DOC Skimmer 9001, a true plug-and-play skimmer for small marine aquariums from 20 to 140 liters. It doesn't need complicated settings or regular calibration to function. Just mount it in the corner of the aquarium and it will do the job on its own.

Flash Skimming

The Flash Skimming principle ensures effective foam production and high machine performance.
Principle: The protein-rich surface water layer is very intensively mixed with air by the TUNZE® Foamer. During the formation of air bubbles, waste such as proteins, cellulose, dead cells, etc., are collected on the surface, resulting in small bubbles with a diameter of 0.1 and 0.3 mm. The mixture of water and air bubbles is relaxed and stabilized in the skimmer, then the water returns to the aquarium and the air bubbles with the proteins move to the foam tank reactor. The patented Anti Overfoaming system – an intermediate chamber with a water distributor prevents the skimmer from boiling and regulates foam efficiency according to the water level and biological load.

With Flash Skimming, particularly high efficiency can be obtained compared to modular skimmers with long contact time, because in this case, the substances absorbed by the bubbles do not detach but return to the aquarium water.
