JEREPET Aquarium Wave Maker, 2100 GPH Mini Powerhead with Controller

JEREPET Aquarium Wave Maker is a compact, controllable powerhead for saltwater and freshwater tanks, delivering up to 2100 GPH (7,949 L/h) and designed for aquariums from 50 to 100 gallons (189 to 379 L).

• Up to 2100 GPH flow from a 12 W pump — creates water movement for suitable aquariums.
• Digital display and adjustment knob — let you select operating modes and control.
• Pulse, steady-stream and 10-minute feed modes — support different tank routines.
• Magnetic mount for glass up to 12 mm (1/2 inch) thick — secures the pump in compatible tanks.
• Sine-wave control technology with noise below 25 dB — keeps pump operation quiet.

Water movement is an important part of aquarium setup, including in coral reef tanks. This compact wave maker gives aquarists adjustable flow options in a pump intended for saltwater or freshwater aquariums, with a controller for changing modes and managing the pump.

What tank size and aquarium types is this wave maker for?

JEREPET is designed for tanks from 50 to 100 gallons and works with both saltwater and freshwater aquariums. Its pump measures 2.7 x 2.7 x 2.2 inches (6.9 x 6.9 x 5.6 cm), making it a mini-format powerhead for creating a wide flow range. It is also suited to coral reef tank setups.

• Maximum flow: 2100 GPH.
• Power: 12 W.
• Compact pump dimensions for aquarium placement.

How do the controller and wave modes work?

The external controller combines a digital display with an adjustment knob for selecting and controlling the pump’s modes. Choose pulse wave mode for changing flow, steady-stream mode for continuous flow, or the 10-minute feed mode. Master-and-slave control is also available for coordinating operation.

• Digital readout and knob control.
• Three named modes for flow and feeding routines.
• Master-and-slave control capability.

How does the pump mount, and what helps protect aquarium life?

The magnetic mounting system is covered with rubber and fits aquarium glass up to 12 mm (1/2 inch) thick. A foam guard covers the rear of the fan to help prevent fish and other things from being sucked in. The pump runs on DC 24 V with external control and no drive inside the pump; the design is intended to support longer pump life.

• Check that the tank glass is no thicker than the supported maximum.
• Foam protection is positioned at the rear fan area.
• Sine-wave control technology keeps noise below 25 dB.

This wave maker suits aquarium keepers seeking adjustable circulation in a 50- to 100-gallon saltwater or freshwater setup, including coral reef tanks. Its compact pump, mode-selecting controller and magnetic mount make it a controlled-flow powerhead for aquariums within its stated size and glass-thickness limits.
