The AI Orbit 2 Flow Pump generates a cross-flow current that mimics the tidal movement of a natural ocean reef, lifting detritus and excess nutrients off the substrate so your filtration can remove them — a different flow pattern from a standard directional circulation pump. Best for: approximately 20 to 88+ gallon tanks Max glass thickness: 0.59in (15mm) Power: variable, up to 25W Control: myAI® or Mobius app (iOS/Android); integrates with Neptune Apex Fusion and the MXM module Orbit is designed to complement, not replace, a Nero or similar circulation pump — Orbit's systematic cross-flow handles detritus lift-off while a Nero-style pump provides the directional and random flow patterns that round out a natural-feeling reef current.Compatible replacement parts: propellers and mounting magnets for the Orbit 2.
