Advanced Cross-Flow Aquarium Technology

The Hygger HG070 uses a cylindrical cross-flow design to generate broad water movement throughout the aquarium.

Traditional powerheads typically direct water through a relatively narrow outlet. Cross-flow pumps distribute water across a wider area, creating a sweeping current that can more closely resemble certain natural water movements.

Broad Water Distribution

The elongated pump body moves water across a wider section of the aquarium.

Natural-Looking Currents

The HG070 can create pulsing, alternating, random, and continuous water movement.

Improved Circulation Around Rockwork

Broad currents help move water around aquarium decorations and live rock structures.

Reduced Low-Flow Areas

Correct placement can help reduce stagnant zones where debris accumulates.

Flexible Aquarium Circulation

The different operating modes allow users to create flow patterns suited to their aquarium's size and inhabitants.

Reef Aquarium Applications

Cross-flow circulation is particularly useful in marine aquariums where water movement is important for many corals and other organisms.

Five Customizable Wave Modes

The Hygger HG070 features five operating modes controlled through its intelligent LCD controller.

Each mode produces a different water movement pattern.

The flow intensity and wave frequency can be adjusted using the controller.

Ideal applications include:

• Creating rhythmic aquarium currents

• Producing visible surface movement

• Simulating repeated wave action

• Adding circulation to compatible reef aquariums

M2 – Sine Wave Mode

Sine Wave Mode gradually changes the flow intensity in a smooth, wave-like pattern.

The manufacturer describes flow variation between approximately 30% and 100% during this mode.

Ideal applications include:

• Creating smoother changes in water movement

• Reducing abrupt transitions between flow levels

• Producing natural-looking aquarium currents

• Supporting compatible marine and reef environments

M3 – Constant Wave Mode

Constant Wave Mode provides continuous water movement at a selected flow setting.
