ComlineŽ DOC Skimmer 9004
The ComlineŽ DOC Skimmer 9004 is rated for saltwater aquariums up to 250 litres (66 US gal) or low-nutrient systems (such as SPS tanks) up to 150 litres (40 US gal). The 9004 draws water from the water's surface helping to eliminate surface slick. A Tunze Foamer 9004 pump quietly generates the foam using their patented self-adjusting "anti-overfoaming system." Tunze refers to the DOC Skimmer's short-contact-time-skimming as "flash skimming." The 9004 comes with an air flow valve and silencer.
