Who it is for
Good fit for
- ✓ 80-500 gallon systems, per the catalog fit range.
- ✓ About 135 gallons of mixed reef or 200 gallons of soft coral on its own.
Not a fit for
- ✕ Tanks under about 80 gallons; it is sized above them.
- ✕ Systems over about 500 gallons without adding capacity elsewhere.
- ✕ SPS tanks over about 80 gallons unless paired with more flow.
Listed features
- DC controllable via myAI/Mobius app
- broad propeller flow
- multiple flow modes
Compatibility math
Turnover contribution
Example: 4,000 GPH contributes about 53x turnover on a 75g tank before placement and mode settings.
The planner adds all flow pumps together and compares the total to the reef goal.
Risk notes
- Too little flow leaves dead spots. Too much direct flow can strip tissue from LPS and irritate soft corals.
Professional fit context
- Check controllability, broadness of flow, glass thickness, GPH range, and whether two smaller pumps beat one large one.
- AquaIllumination Nero 7 Wave Powerhead (4000 GPH) fits roughly 80-500 gallon systems; confirm that range against the final display volume, sump volume, and livestock plan.

Questions
How many AquaIllumination Nero 7 Wave Powerhead (4000 GPH) pumps does a 75 gallon mixed reef need?
A 75 gallon mixed reef wants about 2,250 GPH of total flow by ReefCrafter's 20-40x rule. At 4,000 GPH rated, that is about 1 of these at full output, before return-pump flow and mode settings.
What tank size is the AquaIllumination Nero 7 Wave Powerhead (4000 GPH) for?
ReefCrafter's catalog fit range for it is 80-500 gallon systems. Confirm that against your final display volume, sump volume, and livestock plan rather than the box label alone.
