5. Setup
Follow these steps to properly set up your SOW-8 Wave Maker:
- Mount the Pump:

Figure 5.1: SOW-8 Wave Maker pump unit.
Position the wave maker pump unit inside your aquarium. The pump typically attaches to the aquarium glass using strong magnets. Ensure the pump is fully submerged and positioned to create the desired water flow without disturbing substrate or corals excessively. The pump's outlet can be rotated 180 degrees to adjust flow direction.
- Connect to Controller: Connect the cable from the wave maker pump unit to the designated port on the external controller. Ensure the connection is secure.
- Connect Power Adapter: Plug the power adapter into the controller. Then, plug the power adapter into a standard 100V 60Hz electrical outlet.
- Initial Power On: Once connected, the controller will power on. Observe the pump for initial operation.
6. Operating Instructions
The SOW-8 controller allows for various modes and adjustments:

- Mode Button: Press to cycle through different wave patterns (e.g., constant flow, pulse mode, random flow). Refer to the controller's indicators for the active mode.
- Speed/Feed Button: Adjusts the flow intensity. A short press may change speed, while a long press typically activates a "feed mode" which temporarily pauses the pump for feeding.
- Lock Button: Locks the current settings to prevent accidental changes.
- Night Sensor: The built-in light sensor on the controller automatically detects when aquarium lights are off and reduces pump activity to a gentler flow, mimicking natural nighttime conditions.
- Master/Slave Function: For multiple SOW wave makers, one controller can be set as "Master" to control other "Slave" units wirelessly, ensuring synchronized wave patterns across the tank.
Experiment with different modes and speeds to find the ideal water movement for your specific aquarium inhabitants and setup.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your SOW-8 Wave Maker:
- Monthly Cleaning: Disconnect the pump from power. Remove the pump unit from the aquarium. Disassemble the impeller cover and impeller. Clean all components, especially the impeller and its housing, using a soft brush and warm water to remove algae, detritus, and calcium buildup. Do not use harsh chemicals.
- Inspect Cables: Periodically check the power cables and connections for any signs of wear, fraying, or damage.
- Controller Care: Keep the controller dry and clean. Wipe with a dry cloth if necessary.
- Reassembly: Ensure all parts are correctly reassembled before returning the pump to the aquarium and reconnecting power.
8. Troubleshooting
If you encounter issues with your SOW-8 Wave Maker, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not operating | No power; loose connection; damaged power adapter/controller. | Check power outlet. Ensure all cables are securely connected. Inspect power adapter and controller for damage. |
| Weak or inconsistent flow | Impeller clogged with debris/algae; calcium buildup; pump not fully submerged. | Disconnect power and clean the impeller and pump housing thoroughly. Ensure pump is fully submerged. Adjust speed settings on controller. |
| Unusual noise from pump | Debris in impeller; worn impeller; improper installation. | Disconnect power and clean the impeller. Check for any foreign objects. Ensure pump is securely mounted and not vibrating against the glass. |
