- 5-year warranty
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.
- Sicce Syncra Silent 1.5 Pump (357 GPH) fits roughly 15-40 gallon systems; confirm that range against the final display volume, sump volume, and livestock plan.
Alternatives to compare
- Sicce Syncra SDC 3.0 WiFi Controllable Pump (260-800 GPH)
260 GPH vs 357: less flow for smaller systems.
- Sicce Syncra Silent 1.0 Pump (251 GPH)
251 GPH vs 357: less flow for smaller systems.
- Sicce Syncra SDC 6.0 WiFi Controllable Pump (530-1450 GPH)
530 GPH vs 357: more flow.
