In this video, we're going to look at the Tunze  9004 Comline DOC Protein Skimmer. We're really excited to show you guys this skimmer because it's got some really great features that you're not going to see in a lot of skimmers out there.

This skimmer packs a big punch for a small box: the footprint is only 4 square inches and it measures 12" tall! Tunze's rated the skimmer for mixed reef aquariums up to 65 gallons or SPS-dominant aquariums up to 40 gallons. That's pretty impressive for a skimmer its size.

One of the key features of this skimmer is the surface intake. The surface intake pulls all of the water going into the protein skimmer from the surface of your aquarium. Now this is critical because the surface water of your aquarium is where unwanted waste and proteins are most highly concentrated. The skimmer can therefore pull this unwanted waste and protein out of your aquarium much more efficiently than a skimmer that pulls from below the water surface.

The Tunze Foamer Pump is foam-producing machine. It creates a massive amount of foam with only 4-watts of energy consumption. It comes standard with a needlewheel impeller to create fine foam and it runs very quietly. You're also going to get the air silencer that will eliminate any air noise created from air getting drawn into the water pump.

Keep in mind this skimmer is intended for in-tank use only. It's going to work best in a system with a constant water level. Be sure that your auto top-off system or Tunze Osmolator is in working order or you might want to look into investing in one before installing this skimmer in your home aquarium.
