The Ideal Submersible Pump for Larger Aquariums-- All Flow, No Compromise

  • Max Flow - 4000 GPH
  • Perfect for tanks 80-500+ Gallons!
  • App control with MyAI or Mobius
  • Compatible with glass thickness up to .79"
  • Compact design - just 3.38" in diameter!


Like the Nero 3 & 5, the Nero 7 utilizes an innovative propeller design which creates an adjustable broad flow that is both strong and gentle. The Nero 7 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.


Easy App Control

The Nero 7 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. 


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.


Flow Modes

Random: The Nero 7 will randomly change its flow rate throughout the day simulating a high-energy reef environment.

Pulse: Used to create a standing wave in your aquarium. The pulse interval and max flow rate can be changed based on the needs of your aquarium. Pulse is a great method for lifting settled detritus from hard-to-reach areas. 

Constant: Set the appropriate flow rate and the Nero 7 will keep flowing at that speed until you change the mode or flow. 

Schedule: Using the MyAI or Mobius app, create a schedule that can utilize multiple different flow modes.

Feed: Just hold the driver button for 2-5 seconds to put the Nero 7 into feed mode for 10 minutes. 

All-Off: Hold the driver button for 6 or more seconds to turn the pump off. Touching the button again will restart the pump. 


Magnetic Mounting

The included magnetic mounting system makes installing the Nero 7 effortless. Giving around 15° of movement, you can direct the flow where your tank needs it most. 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. 


Included Fish Guard

The fish guard offers more safety to slow-swimming and curious inhabitants.

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.
