3. Setup
3.1 Charging the Feeder
Before initial use, ensure the feeder is fully charged. Connect the provided USB charger cable to the feeder's charging interface and a suitable USB power source. It is recommended to charge for at least 10 hours for the first time to ensure optimal battery performance. The indicator light will signal charging status.

3.2 Installing the Feeder
The feeder offers two convenient installation methods:
- Method 1: Adjustable Clamp
Attach the feeder to the rim of your aquarium tank using the adjustable clamp. Ensure the clamp is securely tightened. This method is suitable for tank glass with a thickness of less than 24mm. The rotatable base allows for precise positioning over the feeding area.
- Method 2: Double-Sided Sticker
For tanks with lids or other suitable surfaces, use the included double-sided sticker to adhere the feeder to the tank's top cover. Ensure the surface is clean and dry before applying the sticker for a secure bond.

3.3 Loading Food
Open the loading sliding cover on the top of the feeder. Fill the 200ml capacity container with your preferred type of fish food, such as pellets, granules, powders, or strips. After filling, close the sliding cover securely.

4. Operation
4.1 Setting Feeding Intervals
The feeder offers three smart interval modes for automatic feeding:
- Press the "12" button to set the feeder to dispense food every 12 hours.
- Press the "24" button to set the feeder to dispense food every 24 hours.
- Press the "48" button to set the feeder to dispense food every 48 hours.
Once a button is pressed, the feeder will automatically rotate once at the selected interval, starting from the time of activation.

4.2 Manual Feeding
To dispense food immediately, press the "MANUAL" button. This allows for instant feeding as needed, without affecting the programmed automatic feeding schedule.
5. Maintenance
5.1 Cleaning
The feeder is designed for easy maintenance. For cleaning, it is recommended to hand wash the food container and any parts that come into contact with food. Ensure the electronic parts are not submerged in water. Allow all components to dry completely before reassembly.
5.2 Food Storage
Regularly check the food container to ensure the food remains dry and free from moisture or clumping. This is particularly important for flake food, which can be prone to static electricity and uneven distribution. Refill the food container as needed to ensure continuous feeding.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Feeder not dispensing food. | Low battery; food jammed; feeding slider closed. | Charge the feeder; clear any food blockages from the dispensing mechanism; adjust the feeding slider to the open position. |
| Feeder dispensing too much/too little food. | Incorrect feeding slider adjustment. | Adjust the feeding slider to precisely control the dispensed amount. For flake food, careful adjustment may be needed to prevent overfeeding or underfeeding due to static electricity or uneven distribution. |
| Feeder not turning on. | Battery depleted. | Charge the feeder for at least 10 hours. Ensure the USB cable is properly connected. |
| Feeder not securely attaching to tank. | Clamp not tightened sufficiently; sticker not applied correctly or surface is dirty. | Ensure the adjustable clamp is securely tightened to the tank rim (max 24mm thickness). If using the sticker, ensure the tank surface is clean, dry, and smooth before applying. |
