Maintenance
1. Cleaning
Regular cleaning of the food container and dispensing mechanism is recommended to prevent food buildup and ensure proper operation. Disconnect the feeder from the aquarium and disassemble the food container for cleaning. Use a soft, damp cloth to wipe surfaces. Ensure all parts are completely dry before reassembling and refilling.
2. Moisture Control
The feeder features a retractable food dispensing port and a rubber stopper to prevent moisture intrusion and clogging. Always ensure the food container is sealed properly after refilling. Store dry food in a cool, dry place to maintain its quality and prevent clumping within the feeder.
