The “Nano” model series has been designed for the use in reef biotopes up to 200 litres (52 US gal.), and is gentle to the plankton in operation. The DOC Skimmer 9002 removes up to 80 per cent of organic waste matter, such as protein and cellulose, from the aquarium water. Very little space is required in the aquarium, and its handling is very easy. On account of their construction, these models are particularly quiet during operation. On account of the high demands in stone coral aquariums, this skimmer should be used only in aquariums with about 100 litres (26 US gal.) of water. Mixed aquariums or soft coral aquariums up to 200 litres (52 US gal.) can be set up without any problems.
Delivery condition: Completely ready for mounting with holding device for vertical panes and horizontal glass tops up to 39 mm (1.5 in).

By means of the water jet of the Nano pump and a high-performance jet, a fine pearly air mixture is produced which is released into an easy-to-clean skimmer cup through a newly developed reflection system. The protein-containing aquarium water diffuses into the skimmer through the opening in the bottom and on the rear, which is gentle to the plankton, thus suitable in particular for breeding tanks with living plankton.
