- Continuous Filtration: Allow the filter to run continuously for optimal water clarity and health of aquatic life.
- Flow Rate Adjustment: If your model includes a flow rate adjustment feature, you can modify the water flow to suit the needs of your aquarium inhabitants. If low flow is desired, adjust the flow rate accordingly.
- Water Circulation: The filter helps create natural currents in both freshwater and marine aquariums, which is beneficial for fish and plant health.

6. Maintenance
Regular maintenance is crucial for the longevity and efficient performance of your SOBO WP-3000F filter. Performing regular maintenance can prolong the lifespan of the pump.
- Disconnect Power: Always unplug the filter from the electrical outlet before beginning any maintenance.
- Remove from Aquarium: Carefully remove the filter from the aquarium.
- Disassemble: Gently open the filter housing to access the internal components.
- Clean Filter Sponge: Remove the filter sponge and rinse it thoroughly with clean aquarium water (not tap water, to preserve beneficial bacteria) to remove accumulated debris and restore proper water flow.
- Clean Impeller and Cover: Clean the impeller cover and the impeller assembly. Remove any debris, algae, or mineral buildup that may hinder its rotation.
- Clean Intake Screen: The specially designed intake screen should also be cleaned. While it reduces cleaning frequency, it may become obstructed, especially in heavily stocked aquariums.
- Reassemble: Once all components are clean, reassemble the filter, ensuring all parts are securely in place.
- Reinstall: Place the filter back into the aquarium, ensuring it is fully submerged before reconnecting power.
Note: The frequency of cleaning depends on the bioload of your aquarium. It is recommended to check the filter sponge weekly and clean as needed.
7. Troubleshooting
If the SOBO WP-3000F filter pump fails to operate, perform the following checks:
- No Power:
- Check if the power plug is securely connected to the electrical socket.
- Verify that there is a normal power supply to the pump and motor by testing the outlet with another appliance.
- Reduced Flow or No Flow:
- Disconnect power and remove the filter from the aquarium.
- Check if the outlet and intake ports are clear of any obstructions.
- Inspect the impeller for any debris, hair, or foreign objects that might be preventing it from spinning. Clean the impeller and its housing thoroughly.
- Examine the filter sponge and intake screen for excessive clogging. Clean or replace the filter sponge if necessary.
- Unusual Noise:
- Disconnect power and check the impeller for any foreign objects or damage.
- Ensure the filter is fully submerged and securely mounted, as vibrations can cause noise.
If the problem persists after performing these checks, please contact customer support.
