With the EHEIM Feeding Station, you give your fish their meals underwater. When you feed your fish, the food usually floats on the surface of the water. It gets spread around in an uncontrolled manner. What is not found and eaten immediately, disappears into the background and filter. It decomposes little by little and loads the water. That's it with the EHEIM feeding station: it is now possible to feed the food from the feeding cylinder in a targeted way under the water. The fish are already waiting for it. It is almost impossible for it to drift. Everything is eaten and the water stays clean longer. The advantage also is that you can observe and control all the fish on the feeding station.
