Tunze Comline DOC Protein Skimmer 9004 Information

Product Manuals & Documentation

The new Tunze Comline® filters opens the way for compact aquarium components designed for internal operation, are ultra-functional and are highly-sophisticated. The system creates a natural atmosphere in the aquarium at a minimum size. The goal always remains the same, more performance and less space.

The Comline® DOC Skimmer 9004 is designed for use in seawater mixed aquariums / soft coral aquariums up to 250 litres (66 USgal.) or sensitive reef biotopes with stone corals up to 150 litres (40 USgal.). It works based on the TUNZE® Flash Skimming principle, water supply is provided via an efficient surface intake system with bacteria film removal. Thus, the system can also be used as a “standalone solution” in the aquarium. The featured TUNZE® Foamer generates many fine air bubbles with a diameter between 0.1 and 0.3mm, which ensures particularly silent operation.

The “Flash skimming” principle enables highly efficient foam production.
Principle: Protein-rich surface water is mixed with water thoroughly in the TUNZE® Foamer. On the surface of the air bubbles forming, pollutants such as protein, cellulose, dead cells, etc. are adsorbed immediately, the air bubbles are very fine, with a diameter between 0.1 and 0.3mm. The water/air mixture is expanded and stabilized in the skimmer cup, the water returns to the aquarium, and the protein-loaded air bubbles reach the skimmer cup reactor. The patented anti-overfoaming system intermediate chamber with phase water prevents the skimmer from overfoaming and controls the skimmer performance, depending on the water level and organic load.
The particularly high efficiency of the “flash skimming” principle compared to large skimmers with long contact time is obtained because the substances adsorbed by the air bubbles are not released again, thus they don't return to the aquarium water again.

Tunze Awesomeness Product Review by Jabudda (Posted on 9/15/13)

Comments: I have been running this skimmer for about 5 weeks, it's located in the Aqueon 1 sump, in the center chamber with a Tunze Silence Pump in the center chamber as well. I have not experienced micro bubbles. The intake of the skimmer is faced toward where the water enters the sump. It took a while to adjust the speed of the pump, along with the water level & height of the skimmer. The Auto Top Off helps to maintain a stable water level. Ironically, the ATO is also the Tunze Osmosolator. I do prefer Tunze equipment but have tried many inferior products over the last 20 years. Now, I just spend the money to do it right the first time & save the frustration. The reason I chose the center chamber for the Skimmer was the water height was optimal & the flow rate was a bit faster. The last chamber is where my refugium is located. It is the largest section & slowest water movement since the return pump is in the center chamber.

Great little skimmer! Product Review by PAUL (Posted on 8/28/13)

Comments: Just added this to my Innovative Marine Nuvo 38 tank. Previously had the Innovative Marine SkimMate. This is so much nicer. Very easy to install, much quieter than the IM skimmer, and I have not had the microbubble issue that I did with other skimmer. Construction is solid, doesn't feel like I am going to break it. Skimming cup seems smaller than the IM cup, but not a big deal. So far it is skimming great, getting all sorts of stinky stuff out of there!

let it skim! Product Review by ERNEST WEGIEL (Posted on 8/22/13)

Comments: the build quality of this skimmer is durable. The installation is easy as well. I has this for about a week and as soon as the break in was done it skimmed like no other. please do not freak out about the micro bubbles seeping into your tank this will go away. i have very happy about this purchase. The closest thing to this skimmer is a hydor nano. I deff recommend this to anyone who is new to tunze line of products. BY FAR THE MOST DURABLE SKIMMER I EVERY OWNED.

Great so far Product Review by CHRIS KIM (Posted on 1/4/13)

Comments: Just received this skimmer and fits perfectly in my Nuvo 38. It is VERY quiet and has already produced a good foam head. I guess i'll see how it runs in the long run, but for now its already A+!

Tunze Comline Skimmer... Product Review by OMAR ORTIZ (Posted on 2/2/13)

Comments: I saw some of the reviews on here and I wanted to give the product a good review. I don't have the microbubble problem that others seem to have. I am guessing that these issues are more system specific. I think the big downside to this skimmer is the surface skimming is a bit finicky and it works best when the water level is closest to the bottom of the grill. Once you figure out how to tweak it with an automatic top off, you are set.
