The Comline® DOC Skimmer 9004 is designed for use in seawater up to 250 liters (66 US gal.). It operates according to the Tunze® Flash Skimming Principle and acquires the water through an efficient surface suction with a surface film removal, and can therefore also be used as a "stand-alone" solution in the aquarium. The TUNZE® Foamer generates large volumes of fine air bubbles with a diameter of between 0.1 to 0.3 mm (.0039 to .011 in.) and is especially quiet during the operation.

The Comline® DOC Skimmer with a magnet holder for glass up to a thickness of 12 mm (1/2”) is supplied installation-ready.

• Surface intake with bacteria film removal.
• Skimmer cup, 0.2L (.05 USgal.) volume, also accommodates the foam reactor, easy to remove.
• Attachment with a patented magnet holder for a glass thickness of up to 12mm (3/8").
