AI Nero 5 — Reef Wavemaker Pump 3000 GPH Bluetooth Mobius 40-100 gal - AquaIllumination

The AI Nero 5 sits in the middle of AquaIllumination's powerhead line: up to 3,000 GPH from a housing whose wet side measures 2.1 x 2.8 inches. AquaIllumination rates it for aquariums from 40 to 100 gallons. Run it from an app, or from the single button on the onboard controller.

Broad Flow, Not a Jet

This is the Nero line's signature. A traditional propeller design produces a hard, concentrated stream that irritates any coral in its line of fire. The Nero's propeller design pushes water in a wide pattern instead: it moves food, detritus, and free-floating particles without blasting corals directly.

That's a powerhead's actual job — kill the dead spots where detritus settles, and keep particles suspended long enough for filtration to catch them. A narrow jet carves a corridor and leaves the corners alone. Broad flow works everywhere.

The 6 Flow Modes

• Constant: fixed flow at whatever rate you set
• Pulse: builds a wave by alternating flow — useful for lifting detritus out of hard-to-reach spots
• Random: randomized variation, the closest thing to a natural reef
• Schedule: a full daily schedule cycling through modes and speeds
• Feed: pauses for feeding
• All-Off: complete shutdown

Control

• MyAI or Mobius app: iOS and Android, both free
• MXM / Apex Fusion: for driving the Nero 5 from a Neptune Apex
• Single-button controller: onboard, for adjusting speed and mode without a phone

Magnetic Mount

The magnetic mount takes glass up to 0.63in. (16mm) and gives 15° of directional adjustment. That's thicker than the Nero 3 handles (0.5in.) — check your glass before choosing, especially on a 40-gallon tank where either model would otherwise be on the table.

A fish guard is included, protecting slow-swimming fish and curious invertebrates.

Nero 5 Maintenance

AquaIllumination recommends a full disassembly and cleaning 4 to 6 times annually as preventative maintenance. The official video below walks through the complete teardown.

What we see in the shop: frequency depends enormously on your tank. An aquarium growing a lot of algae clogs a pump fast — there, you'll be at it often. A clean, stable tank might do fine with twice a year. The real rule is to inspect. When a pump loses flow, nine times out of ten it's a scaled impeller. Deposits build slowly and you never see it coming: flow drops gradually until your corals tell you before you notice yourself.

For soaking, we don't recommend vinegar — it's the old method, and over time it's hard on plastics and rubber components. We stock Delete by Akua Design for this: a descaler built for aquarium equipment that dissolves calcium buildup without attacking the parts. You can even leave the pump running in the solution for a hands-off clean.

Nero 3, 5, or 7?

AquaIllumination's recommended ranges:

• Nero 3: up to 2,000 GPH — aquariums from 5 to 60 gallons — glass up to 0.5in.
• Nero 5: up to 3,000 GPH — aquariums from 40 to 100 gallons — glass up to 0.63in.
• Nero 7: up to 4,000 GPH — aquariums from 80 to 500+ gallons

The Nero 5 overlaps the Nero 3 between 40 and 60 gallons, and the Nero 7 between 80 and 100. In those bands, your corals decide: an SPS tank appreciates the bigger model's headroom, an LPS or soft coral tank is well served by the smaller one.

And often, two pumps beat one big one. Two Neros facing each other and synced in Mobius create alternating movement a single pump can't reproduce, even at the same total flow.

Complementary products:

• AI Nero 3 — 2,000 GPH, for tanks from 5 to 60 gallons; also an excellent second pump alongside a Nero 5
• AI Nero 7 — 4,000 GPH, for systems from 80 to 500+ gallons
• Delete — Akua Design Descaler — for the impeller soak at those 4 to 6 recommended annual cleanings: dissolves calcium buildup without attacking plastics and rubber
• AI Orbit 2 — cross-flow pump: a transverse sheet of flow rather than a point source, a different approach to circulation

Frequently Asked Questions

What's the difference between the Nero 3 and the Nero 5 for my reef tank?

Flow and glass thickness. The Nero 3 delivers up to 2,000 GPH and AquaIllumination rates it from 5 to 60 gallons, with glass up to 0.5in. The Nero 5 reaches 3,000 GPH, covers 40 to 100 gallons, and takes glass up to 0.63in. Both share the same six flow modes and the same Mobius control. Between 40 and 60 gallons either works: your glass and your corals decide.

How often should you clean a Nero 5 pump?

AquaIllumination recommends a full disassembly and cleaning 4 to 6 times a year. Our shop experience: it depends heavily on the tank. An aquarium growing a lot of algae clogs a pump quickly and needs more frequent attention; a clean, stable tank can do fine with two cleanings a year. Best practice is to inspect — a drop in flow is almost always a scaled impeller. For the soak, an aquarium descaler beats vinegar, which is hard on plastics long term.

Is the Nero 5 pump compatible with Neptune Apex?

Yes. AquaIllumination lists control through MXM and Apex Fusion alongside the MyAI and Mobius apps. So you drive the Nero 5 from the same interface as the rest of your Apex system.

What glass thickness does the Nero 5 handle?

Up to 0.63in. (16mm). Measure your glass before ordering: if it's thicker than 0.63in., you need the Nero 7, which takes thicker panes.
