It’s like a form of meditation for me. I can shut everything else out and focus on my aquarium and how it’s doing. So I kinda like it. I hate cleaning the glass though.
It's the bottom that's by the sand that's the worst. After getting a couple of scratches in my tank I now have to take the mag cleaner out and hide it. My wife was the worst about dragging the mag cleaner across the sand on the bottom.
