Tunze Master DOC 9415 Protein Skimmer.
**** PRODUCT MANUAL ****
The Master DOC skimmer model series have been designed for use in aquarium cabinets and can operate with a variable water level without modification of the foam production. Their high air output is suitable especially for large livestock in the tank or sensitive hard coral aquariums, and can also be used as a “stand-alone solution” for complete filtration. The Master DOC skimmers are ergonomical, efficient and absolutely “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 150 µm acrylic wadding fibres with little biological action only. This ensures that no unwanted nutrients 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; its spare filter can be replaced easily.
The advantages of the “anti-overfoaming system”
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, addition of new corals, et cetera.
“Anti-foaming 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 constantly into the foam reactor; all water levels are ideal for a maximum skimming performance.
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 / 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.
Delivery condition: Ready to mount; dimensions with the cleaning accessories.
