Maintenance
Cleaning the Feeder
Regular cleaning helps maintain optimal performance and prevents food clumping.
- Remove the feeder from the aquarium.
- Detach the food dispensing lid and empty any remaining food.
- Wipe the food hopper and dispensing lid with a damp cloth. Ensure all parts are completely dry before reassembling and refilling.
- Do not use harsh detergents or abrasive materials. Do not submerge the main unit in water.
Desiccant Replacement
