Aquarium feeder whose ventilated chamber keeps the food dry

The EHEIM autofeeder automatic aquarium feeder keeps dry food fresh thanks to an actively ventilated chamber, right down to the last dose. The battery version, with its reservoir of about 100 ml, delivers up to 4 meals a day. The autofeeder+, fitted with a drum of about 125 ml, is set up over Wi-Fi and warns you by e-mail when the supply falls below 30%.

This EHEIM aquarium feeder feeds your fish at set times while you are away, with dry flakes or granules. Its reservoir sits in an actively ventilated chamber, which keeps the food dry despite the humidity rising from the surface of the tank: the flakes do not clump together, and the unit keeps delivering its portions right to the end of the supply.

The battery-powered autofeeder holds about 100 ml and is programmed on the unit itself, for up to 4 meals a day. Each time slot can be set to one of three positions: saved with no dispensing, one turn of the drum, or two turns 1 minute apart. A slider on the drum opens the outlet more or less to dose the portion, while a button above the display triggers an extra meal at any time, without altering the programme. It runs on 2 AA (LR6) 1.5 V alkaline batteries, supplied, and you can place it wherever you like, with no plug or mains supply.

📶 The autofeeder+ on Wi-Fi

The autofeeder+ has a drum of about 125 ml and is controlled over Wi-Fi from a smartphone, tablet or computer, through the browser and with no app to install. You can freely set the feeding times and portions, with one possible fast day each week, picked at random, and protection against overfeeding. The unit shows the level of the reserve and estimates what is left; an email warns you when the drum drops below 30%, then when it is empty. When paired with an EHEIM professionel 5e filter, it changes the filter's flow rate for 10 minutes at feeding time, and it suspends dispensing if that filter is switched off, for example during a water change. It runs on mains power, through a low-voltage power supply, and consumes 3 W.

Dry flakes to fill the drum

The drum is designed first and foremost for flake food, which flows out through the adjustable opening. The staple flake food feeds aquarium fish that eat at the surface and mid-water, and it stays dry in the ventilated chamber right up to the last dose. If your flakes are large, crumble them between your fingers when filling: they will then pass through the opening without forming clumps.

Place the air inlet away from the humidity of the tank

The motor unit draws in air through an opening at the back, and it must neither sit in the humid air that rises from an open tank nor have this opening covered. Position the device so that only the drum extends over the water, and keep it away from the filter outlet and the air stone, whose splashes wet the food. Live or frozen foods must never go into the drum.

🍃 Ventilation and fitting

A ventilated chamber addresses the main weakness of feeders: the humidity rising from the tank makes the flakes swell, clump together and stick to the drum, so the portions shrink as your trip goes on. With air refreshed inside the chamber, the food stays dry and flows freely, which you can check on your return by comparing the level left with what you had planned to use.

On a covered tank, you place the unit on the grille and secure it with the Velcro strap supplied with the autofeeder; several EHEIM lids, including the VARILUX, already have a feeding hatch sized for it. On an open tank or a terrarium, the supplied bracket clips onto the edge of the glass and is tightened with a screw. In both cases, think about the path of the food, which must fall freely onto a clear area of the surface and not onto a plant leaf or the edge of a root.

🥄 Adjusting the portion

The portion is set with the drum's slider, and the right method is to measure it out of the water. Take the unit out, trigger one dispense over a sheet of white paper, then compare what falls with what you usually give by hand; adjust the slider and repeat until you get the same amount. The two-rotation setting, with 1 minute between them, is useful when the fastest fish empty the surface: the second portion gives the slower ones time to feed. With the autofeeder+, the slider also allows very small portions, handy for fry.

🧳 Before you go away

Set the device up at least a week before you leave, and check every day that everything is eaten: that is the time needed to confirm the portion and the number of meals. A reservoir of about 100 ml lasts several weeks on a tank of ordinary size at 2 meals a day, depending on the portion set. Leave with fresh batteries, because when they run low the screen shows LO and the meals continue, then about 3 days later the device switches itself off, so that the drum is not left facing downwards. Rechargeable batteries are not suitable, as their voltage is too low for reliable operation.

In an aquaponic system, regularity matters as much as quantity. The feed you give becomes, after digestion, the ammonia that the biofilter converts into nitrates for the plants, and an identical ration each day gives the bacteria a steady load instead of a spike when you return from a weekend away. With the autofeeder+, e-mail alerts let you monitor the reserve remotely. The article on the nitrogen cycle explains this pathway, and the guide to holidays with aquaponics details the rest of the preparations.

🧽 Care and storage

To clean it, remove the batteries, take the unit out of the tank and separate the drum assembly from the motor unit. The lid and the drum can be rinsed under running water, whereas the motor unit should only be wiped with a soft, dry cloth, with no hard objects or harsh products. Let the drum dry completely before filling it, because feed poured into a damp drum forms clumps. For extended storage, keep the unit clean, without its batteries, and protected from frost. When you change the batteries, do the swap in under a minute: your schedules will then stay in memory.

Large reserve, ventilated chamber or two chambers?

A large reserve, a ventilated chamber, or two foods at once.

Large supply or food that always stays dry? A large reservoir spaces out refills, a ventilated chamber protects the food, two chambers serve two foods. Three questions and the table gives its verdict.
