@knircky, This tool is reflecting as effective and unfortunate to hear that Eheim auto feeder fell into the water. And sometimes it happens but the moment when it happens, it gives the essence of frustration but after that it's fine.

And good to know that you hold aquarium and hope that you hold some beautiful and eye-catching fishes too, i am not aware of this tool but hope that you will going to get some effective suggestions.

Wishing you an great day and stay blessed. 🙂
