A single powerhead pointed at one spot creates a strong jet but poor overall circulation — a stream pump's adjustable, magnetically-mounted design spreads that flow more usefully across the tank. The Sicce Voyager line spans five sizes, from nano-tank models up to a full-size 1600 GPH unit.
Why Adjustable Stream Flow
Being able to aim and adjust a powerhead's output lets you eliminate dead spots and direct flow exactly where your specific aquascape or livestock needs it, rather than accepting whatever angle a fixed mount happens to provide.
Choosing a Size
- Voyager Nano 1000 — 270 GPH — Sicce's smallest stream pump, built for nano and pico tanks needing real circulation in a discreet package.
- Voyager Nano 2000 — 530 GPH — steps up flow from the 1000 in the same compact body.
- Voyager 2 — 800 GPH — the entry point into Sicce's standard Voyager line, built for small to medium tanks needing adjustable, magnetically-mounted flow.
- Voyager 3 — 1200 GPH — sits between the 2 and 4, sized for medium tanks needing more circulation than the entry model.
- Voyager 4 — 1600 GPH — the largest of the standard Voyager pumps, built for larger reef tanks needing strong, adjustable circulation.
Setup Tips
- Confirm glass or acrylic thickness before ordering to ensure magnetic mount compatibility.
- Adjust flow direction to eliminate dead spots rather than pointing every pump the same way.
- Size for total system flow, factoring in your return pump's contribution alongside powerheads.
