Description

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.

Limited edition. Availability is limited and subject to regional restrictions.
