Tunze Protein Skimmers

Comline DOC Skimmers
   

General information

The model series of the Comline DOC skimmers has been developed for an effective and modern protein skimming process in marine biotopes from 200 to 2,000 litres (52 to 528 US gal.). They stand out for their compact dimensions at the same time ensuring a high foam cup capacity, and producing a very high throughput on account of their air capacity of 650 or 1,300 l/h (171 or 343 US gal./h), for example, depending on the model. They can be placed directly in the aquarium or in cabinet systems with a variable water level.

At an immersion depth of 240 to 290 mm (9.4 to 11.4 in.), the Comline DOC skimmer models can be placed easily and discreetly in the aquarium directly. The inlet of fresh water can be set at between 5 per cent and 70 per cent. They can also be used in aquarium cabinets with variable levels from 100 to 280 mm (3.9 to 11 in.). The accessories supplied have to be used to ensure the generation of a constant internal water level. The water circuit is totally open and operates at a fresh-water inlet of 100 per cent; depending on model, a water throughput of 1,200 l/h or 2,400 l/h (317 US gal./h or 634 US gal./h) is achieved, distinctly improving the gas exchange in the aquarium.

In case of operation in aquarium cabinets, the cartridge core on the outlet pipe ensures bubble-free outgoing water. Skimmer cup and foam reactor are one unit in all TUNZE® DOC skimmers. Every cleaning of the skimmer cup leads to the reactor being cleaned at the same time, and thus a very constant and efficient foam production is ensured. During the cleaning process, the Hydrofoamer remains operational and automatically flushes the jet and the air passage.


How do you select the right DOC skimmer for a marine aquarium ?

The Comline DOC skimmer with hydrofoamer has an open water circuit which can be controlled. Apart from the air output, the flow rate of the skimmer determines the output of the DOC skimmer. In addition, due its biotope composition, every marine aquarium has a different sensitivity with respect to the organic load. Based on a standard marine aquarium with soft corals, the data on the suitable skimmer size may differ in other biotopes. For this reason, the aquarium volumes recommended for the skimmer should be reduced in case of sensitive biotopes:

Low sensitivity
In soft coral aquariums with long-polyp corals and anemones, for example, the share in dissolved organic matter may be higher, sometimes it may even be vital. In this type of aquarium, the recommended aquarium volume can be used without deduction.

Medium sensitivity
A medium organic stability is usually found in mixed aquariums inhabited with soft and stone corals (LPS). Filter-feeding animals, sponges, et cetera, are found there frequently as well. For these aquariums, a reduction of about 20 per cent of the skimming capacity is calculated. A skimmer for 1,000 litres (264 US gal.) should thus be used for an aquarium of about 800 litres (211 US gal.) which has this kind of reef design.

High sensitivity
Aquariums with primarily small-polyp stony 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. Comline DOC skimmer is also often used as a “stand-alone” solution in these aquariums. This type of aquarium should be reduced by about 40 per cent in volume for the skimmer volume mentioned.

High sensitivity and high load
Hard coral aquariums with a high population of fish require an extremely high skimming capacity. The skimmer has to ensure the degree of purity for the hard corals at an above-average high fish load. If the Comline DOC skimmer has to operate as a “stand-alone” solution here, a high performance is required. This type of aquarium should be reduced by up to 60 per cent in volume for the skimmer volume mentioned.
