Technical Features

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

Each marine aquarium has, due to an individually created biotope, a different sensitivity to the load of organic compounds. The assumptions regarding the tank size are for the average marine soft coral 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, if necessary, corrected.

Low Sensitivity

In aquariums containing soft corals, such as long polyp corals 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 tanks. 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 of about 600 liters.

High Sensitivity, 60% Reduction

Aquariums predominantly containing SPS (small polyp stony) corals 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 coral 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 for a tank of about 360 liters.
