Orbit 4 — Gyre 45W Cross-Flow Pump 20mm Glass Bluetooth - AquaIllumination

The AquaIllumination Orbit 4 is the high-power version of the Orbit lineup, designed for reef aquariums from 20 to 120+ gallons. With 45W max power and an elongated 12.1 in. (307 mm) profile, it delivers superior cross-flow coverage compared to the Orbit 2. Its circular current simulates the natural tidal flow found on ocean reefs, effectively lifting nutrients and detritus from the bottom for removal by filtration. Compatible with glass up to 0.79 in. (20 mm), it fits large, thick-glass aquariums.

Key Benefits

• Powerful 45W cross-flow technology — circular current for large volumes
• Forward and Reverse modes to create turbulent flow and lift detritus
• 4 flow modes: Constant, Pulse, Random and Reverse
• Bluetooth LE control via Mobius or myAI app — no Wi-Fi hub required
• MXM compatible for control through Neptune Apex and Apex Fusion
• Supports glass up to 0.79 in. (20 mm) — ideal for Red Sea Reefer XL and XXL

Reef Tank Application

The Orbit 4 excels in aquariums from 60 to 120+ gallons where powerful cross-flow current is needed. Combined with a directional pump like the Nero 5 or Nero 7, it reproduces natural reef flow conditions — powerful, directional, systematic and chaotic. Reverse mode flips the flow direction to create turbulence and dislodge detritus. Two Orbit 4 pumps running in opposite directions amplify the gyre flow for complete circulation in large systems.

Installation and Mounting

The Orbit 4 mounts with a magnetic system supporting glass up to 0.79 in. (20 mm) thick. Its elongated 12.1 in. (307 mm) wide profile provides extended flow coverage while only projecting 1.69 in. (42.9 mm) into the aquarium. The integrated controller allows quick adjustments without a smartphone.

Frequently Asked Questions

What is the difference between the Orbit 2 and Orbit 4?

The Orbit 2 delivers 25W and suits tanks from 20 to 88+ gallons with glass up to 15 mm. The Orbit 4 delivers 45W, supports glass up to 20 mm and covers tanks up to 120+ gallons with a wider 12.1 in. profile.

Is the Orbit 4 compatible with Red Sea Reefer aquariums?

Yes. The Orbit 4 supports glass up to 0.79 in. (20 mm) thick, making it compatible with Red Sea Reefer XL and XXL aquariums. It is also MXM compatible for control through Neptune Apex.

Should I combine the Orbit 4 with a Nero pump?

AquaIllumination recommends combining the Orbit (circular cross-flow current) with a Nero (directional flow) to recreate a complete flow ecosystem. The Orbit 4 can also be used on its own to add tidal current to your aquarium.
