Here is my question, thinking about this pump. Max thickness is 5/8 inch glass for the magnet. My glass will be 3/4 inch so I feel like I may be pushing the limits as far as it being able to hold, so I was thinking about attaching it to the overflow glass which will be not as thick. Is there any reason that the magnet on these can not get wet? My thoughts are to attach 2 of them to the center overflow towards the bottom of the tank to keep the back side of my rock and my bare bottom free of debris. I was going to have 1 pointed from the center overflow to each end of the tank.
Thoughts?
