How do you select the right DOC skimmer for a marine aquarium?
Due to its biotope composition, every marine aquarium has a different sensitivity with respect to the organic load. Based on a standard marine aquarium with leather corals, the data on the suitable aquarium size may differ for other biotope compositions. For this reason, the aquarium volumes recommended for the skimmer should be reduced for more sensitive biotopes, if and when necessary.
Low sensitivity, no reductions
In...
leather coral aquariums with long-polyp corals and anemones, for example, the load of dissolved organic matter may be higher, sometimes it may even be vital.
The DOC Skimmer can be used for the recommended aquarium volume without reductions.
Average sensitivity, 40% reduction
Amedium organic sensitivity is usually found in mixed aquariums inhabited with leather and stoney corals (LPS). Filters, sponges, etc. can also be found there. A DOC skimmer that is designed for 1,000 liters (264 USgal.) is likely to only skim 40% of organic substances with this light pollution.
Thus, a DOC skimmer for 1,000 liters (264 USgal.) should be used for a tank with a maximum content of approx. 600 liters (158 USgal.).
Increased sensitivity, 60% reduction
Aquariums with primarily small-polyp stoney corals (SPS) require an especially high degree of purity. They should have no load of phosphates or nitrates worth mentioning. Good oxygen saturation and very clear water are the pre-requisites. In this type of aquarium, the DOC skimmer is frequently used as a "stand-alone solution".
Thus, a DOC skimmer for 1,000 liters (264 USgal.) should be used for a tank with a maximum content of approx. 400 liters (106 USgal.).
High sensitivity and high load,
70% reduction
Hard coral aquariums (SPS) with a high population of fish require an extremely high skimming capacity. The skimmer has to ensure the proper degree of purity for hard corals in case of an excessive fish burdening, whereas an especially high performance is required if it's used as a "stand-alone solution".
Thus, a DOC skimmer for 1,000 liters (264 USgal.) should be used for a tank with a maximum content of approx. 300 liters (79 USgal.).
Especially for Comline® DOC skimmers used as contact skimmers for breeding tanks with plankton, 70% reduction
Stone coral aquariums or other breeding tanks with plankton food require an especially high degree of purity. Good oxygen saturation and very clear water are the pre-requisites.
Thus, a Comline® DOC skimmer for 1,200 liters (317 USgal.) should be used for a tank with a maximum content of approx. 360 liters (95 USgal.)
The TUNZE® Comline® opens the...
way for compact aquarium components for internal operation, ultra functional, sophisticated, with clearly defined lines.
The Comline® is a multi-functional product line: 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, more performance from less space. Comline® components meet these requirements and the visual harmony of the aquarium is maintained. It is no longer necessary to hide technical equipment in the aquarium; instead, it forms an integral part of it. The system is highly effective; all organic pollutants are removed from the environment directly, while the path the water has to cover is short and direct. The risk of leakage is almost zero. The highly efficient technology enables reduction of the volume of the internal equipment, as well as significantly reducing the energy consumption .
Comline® DOC Skimmer 9001
Simple, quiet and effective – these are the current demands towards aquarium components. That is precisely what distinguishes the small Comline® DOC Skimmer 9001 – a true "plug and play" skimmer for small seawater aquariums with 20 to 140 liters (5.3 to 37 USgal.). There is no complicated setting or regular adjustment required for the operation. A simple installation into a corner of the aquarium is sufficient and it will work autonomously.
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 .1 and .3 mm (.004" - .012"). 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 overfoaming 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.
Eelectronically controllable by the Turbelle®...
Controller. Micro-processor controlled PM motor operating on safety extra-low voltage of 12 V to 24 V. Blocking and run-dry protection.

best nano skimmer I've used so far
So far, it's the best nano skimmer i've used to date. I've always been a little intimidated by the tunze skimmers, i guess because they look and function a little differently from many other skimmers. However, I like the fact that they make their own DC pump for this thing, and on my coral QT tank, which is an old JBJ 24G biocube, it works perfectly. I have it in the left-most chamber, but it can also fit into the center chamber. I already had my ATO bracket and some other stuff in the middle, so it worked out better on the left.<br><br>It took a day or two getting it tuned in, but now i'm pretty consistently pulling some skimmate every day. I've got the DC pump set just under half-way, maybe 11 o'clock or so on the dial. The whole tank looks a lot better now that this is on it, not sure if it's just from oxygenation, or the waste removal, or what, but I am very happy so far. I'd tried two other nano skimmers, both were kind of flawed in their own ways and couldn't hold a candle to this tunze.
