2. Product Features
- Tank Compatibility: Specifically designed for 120-300 gallon fish tanks. Not suitable for tanks less than 120 gallons.
- High Flow Rate: Provides a maximum flow rate of 3400 GPH (5.66 Gallons Per Minute) with 40W power and DC 24V voltage.
- All-round Circulation: Features a strong magnetic base for flexible positioning and a rotatable head to direct water flow from multiple directions, creating comprehensive water movement.
- 4 Optional Wave Modes: Easily switch between M1 (Constant Water Flow), M2 (Cuboid Wave Mode), M3 (Sine Wave Mode), and M4 (Irregular/Random Flow) using the control panel.
- Feeding Feature: A dedicated feed mode temporarily stops the pump for 10 minutes to allow fish to feed without food being dispersed by the current.
- Quiet Operation: Engineered for low noise output, producing a mild ringing sound during operation to minimize disturbance.

4. Installation
Follow these steps for proper installation:
- Positioning the Pump: Place the wave maker pump unit inside your aquarium. Use the strong magnetic base to secure it to the tank wall. Ensure the pump is fully submerged in water.
- Adjusting Direction: The rotatable head allows you to adjust the direction of water flow to achieve optimal circulation.
- Controller Placement: Mount the external controller outside the aquarium in a dry, easily accessible location. The controller can be attached to the tank stand or wall using the provided adhesive pad.
- Connecting Power: Connect the pump unit to the controller, and then plug the power adapter into a suitable electrical outlet. Ensure all connections are secure.

5. Operating Instructions
The external controller provides various settings to customize water flow:
- Wave Modes (M1/M2/M3/M4): Press the "MODE" button to cycle through the four distinct wave patterns:
- M1 (Constant Water Flow): Provides a steady, continuous flow.
- M2 (Cuboid Wave Mode): Generates intermittent, strong pulses of water.
- M3 (Sine Wave Mode): Creates a smooth, oscillating wave pattern.
- M4 (Irregular/Random Flow): Simulates natural, unpredictable ocean currents.
- Speed/Feed Control: Use the "SPEED/FEED" button and frequency control knob to adjust the intensity of the water flow (from 30% to 100%). Hold the "SPEED/FEED" button for approximately 3 seconds to activate the 10-minute feeding mode, which temporarily stops the pump. The pump will automatically resume after 10 minutes.
- Light Mode: Press the "LIGHT MODE" button to activate or deactivate the light sensor. When active, the pump's operation may adjust based on ambient light conditions (e.g., reduced power at night).
- Locking Mode: Press the "LOCK" button for 3 seconds to lock the control panel, preventing accidental changes to settings. Press again for 3 seconds to unlock.

6. Maintenance
Regular cleaning is essential to ensure efficient operation and prolong the life of your wave maker:
- Disassembly: The wave maker features a detachable design, allowing for easy disassembly without tools. Carefully separate the pump components.
- Cleaning: Remove any debris, algae, or mineral buildup from the impeller, impeller shaft, and pump housing. Use a soft brush and warm water. For stubborn mineral deposits, a diluted vinegar solution can be used, followed by thorough rinsing.
- Reassembly: Ensure all components are clean and dry before reassembling. Align parts correctly and secure them.

7. Troubleshooting
- Controller Not Working: Check if the power adapter is securely connected and receiving power. Ensure the "LOCK" mode is not active. If the light sensor is on, try turning it off or adjusting the controller's position.
- Pump Not Working: Verify that the pump is fully submerged and that the power cable is securely connected. Check for any blockages in the impeller or housing. Clean if necessary.
- Excessive Noise: Ensure the pump is securely mounted and not vibrating against the tank glass. Check for debris in the impeller. The silicone pads on the magnetic base help reduce noise.
