The Eheim Automatic Twin Feeder is a heaven-sent gift for fishkeepers that enjoy traveling or otherwise just have busy day-to-day schedules. With the ability to quickly and easily program specific feeding times, the unit will help to maintain a consistent feeding schedule for your aquatic inhabitants, reducing the physical stresses resulting from inconsistent feeding. The Eheim Automatic Twin Feeder boasts two separate, spacious food chambers (each with 160 ml capacity) that can hold a wide variety of different types of fish food such as flakes, granules, sticks and pellets. The dual chambers are aerated for maximum freshness and can be independently controlled so that two types of food can be used for feeding at different intervals, depending on the needs of your specific aquarium. Comes with a large, easy to view display with all settings visible, permanent display of time and feeding settings, splashproof function keys and can feed up to 3 times a day. Additionally, the unit features a warning system to alert you of a low battery, and simple press of a button allows you to release random dose of food or “snack” at points throughout the day. Batteries are included and compatible with Varilux aquarium covers. Base size: 4″ x 2.8″.
