Technical Specifications

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

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

Low sensitivity

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 a patch. 

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 maximum tank of about 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 of about 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, it must be particularly efficient.
A DOC skimmer up to 1000 liters should be used for a tank of about 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 of about 360 liters.
