Compatibility math

Head-loss margin

rated GPH should cover 5-10x system turnover after derating

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 0.5 Pump (185 GPH) fits roughly 5-20 gallon systems; confirm that range against the final display volume, sump volume, and livestock plan.
