Turbelle ORCA MK2 Oscillating Mount

Name: Tunze Turbelle ORCA MK2 Oscillating Mount
Brand: Tunze

Robotic sweep

Flow · Powerheads / Wavemakers

Not a pump — a motorized mount that physically sweeps a Tunze Turbelle powerhead ~180 degrees, painting flow across the whole tank from a single point. It adds spatial randomization a fixed pump cannot, and is the elegant fix for far-corner dead zones when all your flow lives on one end (peninsula / long tanks).

Summary

The ORCA MK2 is a carbon-fibre oscillating arm that slowly swings a compatible Turbelle pump back and forth ~180 degrees under app control. Instead of one fixed cone, you get a moving cone that sweeps the tank — so a single ORCA can cover a zone that would otherwise need two or three static powerheads. It's sold mount-only (bring your own Turbelle) or bundled with a 6075; pair it with a bigger 6105 for more swept flow.

Best forPeninsula & long tanks where all flow mounts on one end and far-corner dead zones are the problem Mountmagnetic oscillating arm; app-controlled Skill intermediate

Flow pattern

DC controllable propeller throws a gyre-style flow stream — aim across the tank, not into the rock

What sells it / What holds it back

✓ Pros

✓ Physically sweeps flow — kills far-corner dead zones from one end

✓ One ORCA can replace multiple static powerheads

✓ Reuses a Turbelle pump you may already own (mount-only option)

✓ Tunze build + 10+ yr parts support

✗ Cons

✗ Expensive — mount alone is ~$440 before a pump

✗ A moving mechanical part in saltwater (more to maintain)

✗ Needs a compatible Turbelle pump; no third-party pumps
