5. Setup
- Mounting the Pump: Position the wave maker pump unit inside your aquarium. Use the strong magnetic base to secure it to the aquarium glass. Ensure the pump is fully submerged and positioned to create the desired water flow pattern.
- Controller Placement: Install the control box in a waterproof location, away from direct water splashes. It is crucial to keep the controller dry to prevent damage.
- Power Connection: Connect the wave maker pump to the controller, and then connect the controller to the power adapter. The power adapter reduces 220V voltage to a safe 12V/24V low voltage, preventing the risk of electric leakage and ensuring the safety of your aquatic animals.
- Plug Adapter: Use the appropriate complimentary plug adapter for your region (EU, US, UK, GER, AU, CH PLUG) with the power adapter.



6. Operation
6.1 Control Methods
