- ✓ 40-90 gallon systems, per the catalog fit range.
- ✓ Roughly 70-140 gallon systems at 5-10x turnover after typical head loss.
Not a fit for
- ✕ Tanks under about 40 gallons; it is sized above them.

- ✕ Plumbing runs approaching 13 ft of head, where flow drops toward zero.
Listed features
- QuietDrive
- Mobius app
- backup battery compatible
Compatibility math
Head-loss margin
Example: A 95g system usually wants about 950-1,900 rated GPH if plumbing cuts flow roughly in half.
Return pumps are judged by delivered flow, not only the zero-head box rating.
Risk notes
- Box-rating GPH is measured at zero head. Real stands, elbows, valves, and plumbing cut that number down.
Professional fit context
- Check flow chart, head pressure, controllability, plumbing size, and quiet-mode range.
- EcoTech Marine Vectra S2 Mobius DC Return Pump (1400 GPH) fits roughly 40-90 gallon systems; confirm that range against the final display volume, sump volume, and livestock plan.
Alternatives to compare
- Sicce Syncra Silent 5.0 Pump (1321 GPH)
1,321 GPH vs 1,400: less flow for smaller systems.
- Jebao DCP-5000 Sine Wave Return Pump
1,320 GPH vs 1,400: less flow for smaller systems.
- Jebao DCP-6500 Sine Wave Return Pump
1,710 GPH vs 1,400: more flow.
