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.)

TUNZE DOC Skimmer 9415, 9430 and 9460
The DOC Skimmers 9415, 9430 and 9460 combine very compact design with high performance and are ideal for installation in aquarium cabinets. They feature TUNZE Hydrofoamers 9420.040, 9430.040 or 9460.040 which ensure proper foam production and water circulation at the same time.
Delivery form: Ready to mount. with accessories.

More than 5,000 liters of air per hour with the TUNZE high performance automatic DOC Skimmer” 9460!
In 1963, TUNZE developed the revolutionary first protein skimmer with its own pump and air generator. In 2005, the first TUNZE Flash Skimming models with powerful air injection and low-wattage consumption came onto the market.
Today we designate our low-profile, ultra-efficient skimmers for tighter spaces as high performance automatic DOC skimmers because all models achieve very high standards for quality, performance and ease of use. The DOC Skimmer 9460 delivers an enormous air output of more than 5,000 l/h (1,321 USgal./h) with a very compact design and a water output of more than 3,500 l/h (925 USgal./h). It can be easily used in any aquarium with a cabinet system, but also in professional systems or aquarium stores up to 6,000 liters (1,585 USgal.) of water, the water level can vary between 150 and 250 mm (5.9" to 9.8"). It performs with the amazing TUNZE Hydrofoamer 9460.040 skimmer pump that ensures foam production and water circulation at an energy consumption of only 58 W.

The advantages of the DOC Skimmer 9460:
• High skimming performance with low energy consumption.
• The return water is completely free of bubbles.
• Only high quality materials are used for the DOC Skimmer.
• After the start-up phase, no adjustments are necessary — it works automatically with stable performance.
• The patented Anti-Overfoaming System avoids skimmer overflows and regulates foam production.
• It also captures the energy of output water: The DOC Skimmer contains two removable post-filters that perform a perfect mechanical filtration through 300µm acrylic wadding. The post-filters can be filled with filter media such as loose wadding, activated carbon or phosphate adsorbers.
• Easy cleaning: skimmer cup and foam reactor are one unit.
• Very quiet operation with Hydrofoamer Silence 9460.040 pump — thanks to special silicone feet and an oversized air silencer — this DOC Skimmer 9460 is one of the quietest devices on the market.
• Particularly robust construction of the pump drive: Air injector and high-performance rotor are built in one piece.

Anti Overfoaming System in three steps:
After the improvement of the water parameters, the skimmer returns to the normal operating condition again.

Normal foam production:
The...
foam rises evenly into the foam reactor.

Overfoaming A:
Foam production...
increases due to the surface tension and pulls the bubbles out of the foam reactor.

Overfoaming B:
Foam production...
increases further, bubble production is stopped immediately, foam production is reduced.
