The Comline DOC Skimmer 9004 is designed for use in marine aquariums up to 250 liters (65 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 a large volume of fine air bubbles with a diameter of between 0.1 to 0.3 mm and is especially quiet during operation. Includes magnetic holders for glass up to 1/2".
