The Tunze DOC Skimmer 9430 is a very high performance skimmer with a surprisingly small footprint. It has been designed specifically for use in reef aquaria with a total volume of up to 3,000 litres. It is an internal skimmer, designed to be used in a sump and needs to be immersed in water between 100mm and 200mm deep. It has a power consumption of only 24 Watts, which means that the DOC Skimmer 9430 has an equivalent performance to much larger skimmers that consume significantly more power. In addition, the 9430 Skimmer is quiet and is very simple to operate. The 9430 Skimmer utilizes the Tunze Hydrofoamer Silence 9430.040 pump which has been specifically developed for use with protein skimmers. The Hydrofoamer generates large volumes of fine air bubbles with a diameter of between 0.1 to 0.3 mm. It has an energy consumption of only 24 Watts, and generates an air output of 1,100 litres per hour, which places this air generator at the top of its product class. The optimal water flow of 1,600 litres per hour through the skimmer is also provided by the same Hydrofoamer pump. The DOC Skimmer 9430 has a patented Anti-Overfoaming System®. This prevents overfoaming of the skimmer and regulates the skimming action dependent on both the surface tension of the aquarium water and sump water level. The skimmer operates independently and automatically to maximise its own efficiency. The Skimmer has a nipple for connection to an air pump and ozonizer. Ozone improves the skimming process, raises the redox potential and at the same time removes any yellowing matter in the aquarium water. Finally, a removable 300 µm nylon post-filter, at the outlet of the skimmer, acts as a final mechanical filter, removing any suspended matter that passes through the Skimmer. The post-filter can be filled with other filter media, such as activated carbon or phosphate remover. Replacement filter bags are available as a spare part.
