AquaIllumination Orbit 2 & Orbit 4 Flow Comes Full Circle The AI Orbit series creates powerful cross-flow circulation that moves water throughout the aquarium, closely simulating natural tidal movement found on ocean reefs. This broad flow pattern helps keep detritus suspended for removal by filtration while improving circulation throughout the entire tank. Available in Orbit 2 and Orbit 4, both models feature built-in smart control through the myAI or Mobius app and can also be controlled through Apex Fusion with an MXM module. Features Wide cross-flow circulation Forward & reverse operation myAI & Mobius app control Apex Fusion compatible with MXM Four programmable flow modes Ideal for reef aquariums 20 gallons and larger Works especially well alongside AI Nero pumps for varied, natural flow patterns Flow Modes Constant: Continuous flow at your chosen intensity Pulse: Alternating high and low flow Random: Variable high-energy reef flow Reverse: Reverses the direction of water movement Using two Orbit pumps allows opposing or reversing flow patterns to create even more complete circulation throughout the aquarium.
