AquaIllumination's Nero 3 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 3'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.


Easy App Control

The Nero 3 can be conveniently controlled with the free MyAI or Mobius app - your choice! By connecting your pump to the app, you unlock the ability to choose a flow mode and pump speed as well as the ability to create a full-blown daily schedule that cycles through different modes. 

No smart device? No Problem! The included controller only has one button but is very powerful. Pressing or holding the button for different lengths of time can change the speed, mode, or turn the pump off or on without having to open the app. 


Flow Modes:

Random: Keep your tank guessing with the random flow mode. The Nero 5 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 5 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 5 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 5 into feed mode for 10 minutes. 

All-Off: Turn off your pump whenever you want with full control over when they turn 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. 


Compatible with MXM

Neptune Systems, EcoTech Marine, and AquaIllumination have joined forces to bring MXM to life. Now all your favorite EcoTech and AI pumps and lights can be under the wireless control of Apex & Apex Fusion—the user-friendly, yet powerful, interface you already know and love. No more switching between multiple apps.


Magnetic Mounting

Mounting the Nero 3 only takes a minute and with the included magnetic mounting system moving the pump around only takes a second. Giving 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 1/2\" of glass or less, and the pump then sits into the beveled inner magnet for an isolated and quiet mounting system.

Is there a flow range for these? I see the max is 2000 GPH, but what can this be dialed down to?
Question by: JR Walkenhorst on Jul 1, 2022, 6:09 PM
Thanks for the question! The Nero 3 as well as the Nero 5 can be programmed down to 1%, putting this paritcular model right around 20-40gph when set to 1%. Please let us know if we can help with anything else!

Can this pump be mounted on the back wall of an AIO tank where both magnets would be submerged in water?
Question by: Matt Fierstein on Jan 31, 2022, 1:57 PM
Yes, the magnet is coated and it can be submerged. It is recommended to inspect the magnets from time to time.
Answer by: Matt Lucero (BRS Staff) on Feb 2, 2022, 1:17 PM
Would one of these work for a 48 inch length tank that is mostly softies with a couple of low demand LPS. I don't want hard flow just good water movement.
Question by: Van Webb III on Dec 29, 2021, 11:54 AM
The total gallons would play a factor as well as the length, so it is hard to say without knowing that. A great guide line to take your total volume, say 100 gallons, and times it by 30, so 3000 GPH and if your pump is at that or more, you are fine.
