This skimmer will need an area at least L5.5 x W4.3 x H16.3 in. As long as you are able to check the measurements of the chamber for your tank this skimmer may be able to work well!
The Tunze Comline DOC skimmer utilizes Tunze's "Flash Skimming" principle. The skimmer is quiet and generates a very large volume of small bubbles for efficient skimmer operation. It operates stand-alone without needing any additional equipment (feed pumps, etc) and mounts to the tank via a convenient magnet holder strong enough for glass up to 1/2" thick.
The TUNZE® Foamer generates large volumes of fine air bubbles with a diameter between .0039 to .011 in. (0.1 to 0.3 mm) On the surface of the air bubbles, pollutants such as protein, cellulose, dead cells, etc. are adsorbed immediately. The water/air mixture expands and stabilizes in the skimmer cup reactor, the water returns to the aquarium, and the protein-loaded air bubbles spill over into the skimmer cup. The patented anti-overfoaming system intermediate chamber prevents the skimmer from over foaming and controls the skimmer performance, depending on the water level and organic load. This “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.
Awesome skimmer By Demon-Speeedin on 3/5/2017Demon-Speeedin would recommend this product to a friendBeen using this for over a year, love it. Not sure why the other person had problems with his but mine does not leave air in the system and skims a ton of skimmate out of the tank.
Don't waste your money By Stuart on 2/10/2017Stuart wouldn't recommend this product to a friendI have been using this skimmer off and on for the last 2 years. It released a lot of air bubbles into the aquarium, but other than that I was satisfied with how it worked for the first year. The problems started after the first 12 months. First the impeller broke. They sent me a new foamer under the warranty, but it only worked for 2 months. They sent me a second foamer which did not work right out of the box. After that they just ignored my emails. With some modifications I have managed to keep it working, but this skimmer is not worth all the problems.
