Larger reef tanks need enough flow to keep detritus in suspension and deliver food throughout the water column, and that sometimes calls for more pressure than a standard stream pump provides. The Sicce Voyager HP line steps up to high-pressure output across four sizes.
Why High Pressure Matters at Scale
As tanks get larger and rockwork gets denser, flow needs to push through and around more obstacles to reach every part of the tank — a higher-pressure pump maintains effective circulation in situations where a standard-pressure unit's flow would dissipate before reaching the far corners.
Choosing a Size
- Voyager HP 7 — 2800 GPH — the entry point into the high-pressure Voyager HP line, built for larger reef tanks needing strong, adjustable circulation.
- Voyager HP 8 — 3200 GPH — steps up flow from the HP 7 in the same high-pressure format.
- Voyager HP 9 — 3600 GPH — sized for larger reef tanks needing serious circulation from a single magnetic-mount pump.
- Voyager HP 10 — 4000 GPH — the largest pump in the Voyager HP line, built for large reef tanks needing maximum circulation from a single unit.
Setup Tips
- Reserve HP models for genuinely large or densely-aquascaped tanks — standard Voyager pumps suit most mid-size setups.
- Position to reach rockwork-heavy areas where standard flow would dissipate before arriving.
- Confirm mounting glass or acrylic thickness before ordering.
