TUNZE Manuals & User Guides

TUNZE Aquarientechnik GmbH is a globally recognized German manufacturer of advanced aquarium technology, founded in 1960. The company is renowned for its 'Aquatic Eco Engineering' philosophy, focusing on high performance, energy efficiency, and reliability in aquatic systems.

TUNZE revolutionized the hobby with the invention of the Turbelle powerhead and continues to lead with innovations like the Turbelle® stream pumps for variable flow circulation and the Comline® DOC Skimmers for effective filtration. Their product range also includes the industry-standard Osmolator® auto top-off systems, LED lighting, and filter components designed for both freshwater and marine aquariums.

• What do the LED lights on the TUNZE Osmolator indicate?

  On the Osmolator, a green light typically indicates the water level is correct. A yellow/orange light indicates the pump is running (dosing). A red light usually signifies the safety sensor has been triggered (water too high) or there is a system error.

• How do I clean my Turbelle stream pump?

  To maintain performance, disassemble the pump housing and remove the drive unit. Soak the components in a mild vinegar and water solution to dissolve calcium deposits, then brush clean and rinse thoroughly before reassembly.

• Where should I place the TUNZE skimmer in my aquarium?

  Comline DOC Skimmers should be placed in an area with a constant water level, typically in the sump or a corner of the aquarium. Ensure the immersion depth matches the specifications in your manual (usually between 10-24 cm depending on the model).

• How does the TUNZE safety connector work?

  The Safety Connector allows TUNZE electronic pumps to switch automatically to a battery source (like a 12V-24V battery) in the event of a mains power failure, ensuring continued circulation.
