A propeller-based flow pump pushes a broad, gentle current rather than one concentrated jet, and AquaIllumination's Nero line brings that design across three sizes for nano tanks through large reef systems. All three share the same app-controlled ecosystem as AI's lighting.
Why a Propeller Design
Nero's propeller pushes water in a wide, natural-feeling current rather than a narrow, concentrated jet — closer to how flow actually moves across a natural reef, and gentler on coral polyps and delicate fish than a tightly focused stream.
Choosing a Size
- Nero 3 — the entry point to AquaIllumination's Nero line, sized for smaller tanks wanting real circulation without an oversized pump.
- Nero 5 — the mid-size model, built for 40 to 100+ gallon tanks with the same wide, adjustable flow pattern.
- Nero 7 — the flagship, built for large systems from 80 to 500+ gallons.
Setup Tips
- Size for your tank volume and desired flow pattern, not just raw GPH.
- Use app-based scheduling to build wave patterns and feeding-mode pauses rather than running one fixed setting.
- Position for broad coverage, taking advantage of the wide propeller-driven current rather than aiming like a narrow-jet pump.
