Magnet too strong? By rroselavy on 12/9/2009

This expensive but well-built magnet cleaner has a very strong magnet. On my tank with 3/8" glass, the magnet stutters when wiping off any build-up. The stutter causes vibrations that can disturb the sand if not the inhabitants of my tank. If I move it fast, the stutter goes away, but sometimes causes water to splash out of my rimless aquarium when working at the surface. This is a hassle, so I am now using Kent scrapers and poly pads instead.
This magnet may work just fine on thicker glass, but I think it is too strong for 3/8".
