The characteristic features of the Master DOC skimmer model series are primarily ergonomics and efficiency. It is an efficient unit, which represents a real technical evolution of today's protein skimmers for aquariums. Master DOC skimmer has been designed for the use in aquarium cabinets and can make do with a variable water level without interruption of the foam production. The high air output is beneficial especially for heavy stocking density in aquariums of sensitive hard corals. In a complete filter system, they can also be used as a stand-alone unit. Absolute plug and skim: After the installation and connection of the Hydrofoamer, the units are operational !
In order to use the water energy at the outlet of the skimmer, all Master DOC skimmers are fitted with a removable post-filter which carries out a perfect mechanical filtration through 50µm acrylic wadding fibres with little biological action. This ensures that no unwanted nutrient and nitrate sources develop in case of longer cleaning intervals. The post-filter can also be filled with other filter media, such as activated carbon or phosphate absorbers; the filter can be replaced easily.
The patented “anti-overfoaming system” prevents overfoaming of the skimmer, which occurs, for example, in the following situations:
Organic load caused by dead animal and plant residue or living stones in a newly set-up aquarium.
Increase of the water level in the filter tank.
Use of chemicals, corals, et cetera.
The models of the Master DOC skimmer are easily placed in aquarium cabinets with variable level and need no adjustment for operation. They operate in conjunction with TUNZE® Hydrofoamer 9420.04, which provides the foam production and water circulation at the same time. Depending on the model, the open water circuit thus reaches a water throughput of 1,300 l/h (343 USgal./h), 2,600 l/h (686 USgal./h), 3,900 l/h (1,030 USgal./h) or 5,200 l/h (1,373 USgal./h). The models 9420 (1) / 9440 as well as 9460 / 9480 have the same technical features, only the number of Hydrofoamers varies. Skimmer cup and foam reactor are one unit like 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 air passages.
