A natural reef doesn't move water in one direction — it surges back and forth with the tide, lifting detritus and delivering nutrients across the whole reef structure. The AI Orbit generates that same cross-flow, tidal-style current, in two sizes.
Why Cross-Flow Beats a Single Jet
A standard powerhead pushes water one direction from a fixed point; Orbit's cross-flow design mimics the back-and-forth tidal movement of a natural reef, lifting detritus off the substrate and rockwork and helping distribute food and nutrients more evenly than a single directional stream.
Choosing a Size
- Orbit 2 — generates a cross-flow current that mimics natural tidal movement, sized for small to medium reef tanks.
- Orbit 4 — the larger model, generating the same ocean-mimicking cross-flow current for bigger reef tanks needing more coverage.
Setup Tips
- Position for genuine cross-flow across the tank's width rather than treating it like a standard directional powerhead.
- Use app scheduling to vary tidal timing and intensity throughout the day for a more natural pattern.
- Pair with a Nero or standard powerhead for tanks wanting both cross-flow and targeted spot flow.
The AI Orbit line is available at Marine Concept Supply in both sizes — order online or pick up at our shop in Wheeling, IL. Shop Orbit 2 or Orbit 4, and browse more aquarium pumps.
