Details

Small. Powerful. Smart!

  • Max Flow - 4000 GPH
  • Ideal for Aquariums 80-500+ Gallons
  • App Control with myAI, Mobius, or MXM
  • Compatible with Glass Thickness up to 0.79" (20mm)
  • Fish Guard Included to Protect Tank Inhabitants

AquaIllumination's Nero 7 creates an adjustable broad flow that is strong but gentle at the same time. Traditional propeller designs produce a hard stream that can irritate corals where the Nero 7's innovative propeller pushes water in a wide pattern that can move foods, detritus, or other free-floating particles around without blasting corals directly.

Powerheads have many different uses around a reef tank, but the main goal is to produce enough flow to keep low-flow spots from forming in your tank and help elevate detritus to be sucked into the filtration. With Bluetooth LE technology you can set the pump up into different modes, or create a daily schedule to change the flow up throughout the day.

Powerful Flow in a Compact Footprint

Included Pump Modes

Nero Pumps offer several flow modes to match the needs of your reef, including:

Random: Keep your tank guessing with the random flow mode. The Nero will randomly change its flow rate throughout the day, creating natural water movement throughout your reef tank.

Pulse: Creating a standing wave can be done with the Nero in Pulse Mode. The pulse interval can be changed to harmonize with your aquarium, along with the max flow rate. Having a wave can cause additional stress on your aquarium, but is a great method for lifting settled detritus from hard-to-reach areas.

Constant: Set it and forget it! Just set the appropriate flow rate and the Nero will keep flowing at that speed until you change the mode or flow.

Schedule: Create a schedule that can utilize multiple different flow modes. With the myAI app, creating a schedule for your flow is simple and can be done in minutes!

Feed: If you target feed, having a pump with feed mode is a requirement. Just hold the driver button for 2-5 seconds to put the Nero into feed mode for 10 minutes.

All-Off: Turn off your pump whenever you want with full control over when it turns back on. Just hold the driver button for 6 or more seconds to turn the pump off. Touching the button again will restart the pump.

Magnetic Mounting

Mounting the Nero 7 only takes a minute, and with the included magnetic mounting system, moving the pump around only takes a second. With around 15° of movement, you can angle the Nero to direct flow in your aquarium where you need it.

The two-part mounting system incorporates an inner magnet and an outer magnet that can couple together through 0.79" of glass or less, and the pump then sits into the beveled inner magnet for an isolated and quiet mounting system.

App Control

Connect, control, and program compatible EcoTech and AquaIllumination equipment directly from your iOS or Android device with the Mobius app. Mobius gives you an intuitive way to choose proven templates or create custom programs for your aquarium’s flow and lighting needs, while also helping coordinate compatible smart lights, pumps, and other equipment from one simple control platform.

Product Questions

If I already have one Nero 7 would I need to purchase another one for a 125 6ft tank
Question by: Josh Johnson on Nov 9, 2024, 1:59 PM
If you notice you need more flow, an additional Nero 7 would accomplish this. If it is too much, you can dial down the flow.
Answer by: Grace (BRS Staff) on Nov 12, 2024, 9:15 AM
For a tank of that length we would recommend a second powerhead. We have a helpful guide going over powerhead placement here: www.bulkreefsupply.com/content/post/where-should-a-powerhead-be-placed-in-an-aquarium
Answer by: Laura (BRS Staff) on Dec 27, 2024, 9:20 AM
How Long is the power cord?
Question by: Matthew on May 8, 2024, 9:32 AM
approximately 6 feet
Answer by: Matt Lucero (BRS Staff) on May 9, 2024, 9:50 AM
What is the warranty for these Nero’s?
Question by: Karen Cleaver on Jan 14, 2024, 10:27 AM
Hey there,
Thank you for reaching out to us. One year from date of purchase. Please let me know if you need anything further.
Answer by: Thomas Wofle (BRS Staff) on Feb 1, 2024, 12:47 PM
How wide is the magnet on the Nero 7 Powerhead and each of the smaller units?

I have very limited space between the side of my tank and the cabinet which encloses it, which made me have to drill a hole in the cabinet for the MP 40s. Would be nice to add a second pump without having to drill another hole in the cabinet.
Question by: Ken on Apr 25, 2023, 11:00 AM
Hello, thank you for contacting Bulk Reef Supply customer service. The thickness of the magnets is for the nero 3 is .4 in.
for the nero 5 is .48 in. for the nero 7 is .51 in.
Answer by: Alexander Reinartz (BRS Staff) on Apr 26, 2023, 1:06 PM
What is the angle of flow from nero 7
Question by: peter parkinson on Apr 19, 2023, 7:22 AM
The angle of the flow is adjustable just like the other powerheads in the Nero line!
