TUNZE® ORCA MK2 is a high-quality oscillating unit for circulation pumps, developed through a collaboration between TUNZE® and the German start-up ReefHub. What began as an innovative idea is now being brought into series production: with sophisticated technology, high-quality materials, and our decades of experience in marine aquariums.
TUNZE® ORCA MK2 allows the circulation pump to be moved dynamically in the aquarium: precise and software-controlled by the extremely user-friendly TUNZE® app. This allows changing flow conditions to be created that mimic the natural movement of the sea. In combination with the Reef Assistant app, not only the direction but also the flow strength can be precisely controlled depending on the angle of rotation. The result: less pumping, more movement, and maximum control over the flow.
Specifications
Complete system:
Oscillating unit + pump = plug & play
All from a single source: The TUNZE® ORCA oscillating unit is delivered as a fully coordinated system – including pump, mount, and app connection. Unpack, assemble, and start.
Made in Germany –
real manufacturing expertise
TUNZE® ORCA is built where we bring plastics, electronics, PU encapsulation, and system assembly together every day: in our production facility in southern Bavaria. From the electronics to the cables – many key components come directly from Germany or are manufactured in-house.
5-year warranty –
built for true long-term use
Designed for many years of operation in marine environments – including high-quality German-made drag chain cables. The warranty also applies to wear parts.
Magnetic encoder
for precise position detection
An integrated magnetic sensor precisely measures the pump's alignment. This ensures reliable alignment – without offset, without jumps, and without deviation.
Waterproof & corrosion-resistant
The electronics and control system are fully encapsulated in PU resin. All seals are securely designed. The TUNZE® ORCA oscillating unit is protected against splashes of water and temporary submersion.
Versatile mount
for glass thicknesses up to 22 mm (0.87")
The included mount is suitable for both pools and aquariums with glass ledges. Installation is tool-free, secure, and flexible.
Finely adjustable length –
thanks to the carbon fiber tube
The fork tube can be adjusted in fine increments without the need for tools. The high-quality carbon fiber construction allows for flexible height adjustment with high stability.
Control via TUNZE® app
(iOS & Android)
Developed by aquarists for aquarists: The native Reef Assistant App (iOS & Android) offers intuitive control of all movement and flow parameters. And what's more: It will be expanded into a central all-in-one platform for your entire Tunze system – in the future, you will be able to conveniently control all your TUNZE® HUB devices via one app.
Certified medical device power supply –
maximum safety
Medical device-certified power supply with high operational reliability, power reserves, and high efficiency. A strong heart for your TUNZE® ORCA.
