1. Introduction
This manual provides comprehensive instructions for the safe and effective use of your Jainsons Pet Products SOBO WP-950F 3-in-1 Submersible Aquarium Internal Filter Pump. This device is designed to provide filtration, oxygenation, and water circulation for freshwater and saltwater aquariums, including fish and turtle tanks, and small ponds. Please read these instructions carefully before installation and operation.
2. Product Overview
The SOBO WP-950F is a compact and efficient internal filter pump. Its 3-in-1 functionality ensures a healthy aquatic environment by performing three essential tasks:
- Filtration: Equipped with a filter sponge to remove debris and large dirt particles from the water.
- Oxygenation: Enhances water oxygen levels, crucial for aquatic life.
- Circulation: Ensures even distribution of filtered and oxygenated water throughout the tank.
Key features include a powerful yet quiet motor, strong suction cups for secure attachment, and suitability for both freshwater and marine environments. The filter is designed for aquariums approximately 12-14 inches in size.

4. Setup Instructions
- Prepare the Filter: Ensure all components are securely assembled. The filter sponge should be correctly placed within the filtering cup.
- Position the Filter: Place the pump head entirely underwater. It is critical that the pump head remains submerged to prevent overheating and damage to the motor.
- Attach to Aquarium: Use the strong suction cups on the back of the filter to securely attach it to the inside wall of your aquarium.
- Oxygenation Tube (Optional): If using the oxygenation feature, connect the air inlet tube and ensure the end of the tube is positioned outside or above the water level to draw in air.

5. Operating Instructions
- Ensure Submersion: Double-check that the entire pump head is fully submerged in water before plugging it in.
- Power On: Plug the power cord into a suitable electrical outlet. The pump will begin operating, providing filtration, oxygenation, and circulation.
- Monitor Performance: Observe the water flow and oxygen bubbles (if using the air inlet) to ensure proper operation.
6. Maintenance
Regular maintenance is essential for the longevity and optimal performance of your filter pump and the health of your aquatic environment.
- Weekly Sponge Cleaning: Clean the filter sponge weekly to remove accumulated debris. This prevents clogging and maintains efficient filtration.
- Bi-weekly Tank Cleaning: Clean the fish tank every 15 days. It is recommended to recycle approximately 50% of the tank water and replace it with 50% new, conditioned water.
- Impeller Access: The bottom compartment of the filter can be removed to access the impeller for cleaning and maintenance. This ensures the motor runs smoothly and quietly.
Additional tips for maintaining crystal clear aquarium water:
- Avoid Overfeeding: Feed fish only 2-3 times a day. Excess food can decompose and degrade water quality.
- Remove Excess Food: Remove any floating fish food that remains after 5 minutes to prevent water quality reduction.
- Manage Lighting: Limit aquarium lighting to a maximum of 6 hours per day. Excessive light can promote algae growth.
- Do Not Overcrowd: Avoid overcrowding the tank with too many fish, as this increases biological load and makes maintaining water quality more challenging.

7. Troubleshooting
If you encounter issues with your SOBO WP-950F filter pump, consider the following common solutions:
- Reduced Water Flow:
- Check if the filter sponge is clogged. Clean or replace it as necessary.
- Inspect the impeller for debris or blockages. Clean the impeller and its housing.
- Ensure the water inlet is not obstructed.
- Pump Not Starting:
- Verify that the power cord is securely plugged into a working electrical outlet.
- Ensure the pump head is fully submerged in water.
- Check for any visible damage to the power cord or pump.
- Excessive Noise:
- Ensure the pump is fully submerged and not drawing in air (unless using the oxygenation feature intentionally).
- Clean the impeller and its shaft, as debris can cause rattling.
- Check that the suction cups are firmly attached to prevent vibration.
If problems persist after attempting these steps, please contact customer support.
