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.
Tunze Master DOC 9410 Protein Skimmer.
**** PRODUCT MANUAL ****
Skimming, filtering and aerating a saltwater aquarium without power consumption is impossible. But, no unit uses less current than TUNZE® DOC Skimmer 9410. At a power consumption of only 11 W (15 W), the new DOC Skimmer has equivalent performance to much larger skimmers consuming more than twice as much power. In addition, no settings are required; it is extremely silent; it is easy to operate and it is nice to look at.
Skimmer cup (diam. 160 mm (6.2 in.)) with large capacity; also contains the foam reactor; can be removed easily.
The booster ring permits a fine adjustment of the performance, thus adapting the water level inside the skimmer as required for the production of somewhat wetter foam, for example.
The removable post-filter at the outlet of the skimmer permits perfect mechanical filtration through 150 µm acrylic wadding fibres with little biological action. This ensures that no unwanted nutrient and nitrate sources develop in case of longer cleaning intervals. The filter can be filled with other filter media, such as activated carbon or phosphate absorber.
Stable base which also reduces the water velocity in the lower zone of the skimmer.
TUNZE® Hydrofoamer Silence 9410.04 is a pump specifically developed for protein skimmers. The Hydrofoamer generates large volumes of fine air bubbles with a diameter of between 0.1 to 0.3 mm (.0039 to .011 in.). It has an energy consumption of only 11W (15W) at an air output of 600 l/h (158 USgal./h) which places this air generator at the top of its product class. At a water flow of 900 l/h (1,000 l/h) (237 USgal./h / 264 USgal./h), it is also used to supply the aquarium water to the skimmer.
The mixing chamber with flow distributor binds an especially high amount of organic material.
Intermediate chamber with phase water: The patented Anti-Overfoaming System® prevents an overfoaming of the skimmer and regulates the skimming action according to surface tension of the aquarium water and water level. The skimmer operates independently and automatically sets its best efficiency.
Nipple for ozone connection. Ozone improves the skimming process and at the same time removes any yellowing matter in the aquarium water.

9410 rocks Review by reeftivo
Skimmer rocks but may frustrate people because of the long break-in (two weeks for me). Massive amounts of air for such a small body. The optimum water level for me is 7 inches. It skimmed well after break in but I found that when I trimmed an inch off the output standpipe, it skimmed much dryer for me and that's the way I like it. I also found that running 200 micron mesh instead of felt off the return is much better.
All in all its a great performer. It actually made me shelve my ATB and My BK mini. (Posted on 4/5/2011)
