When I picked my tank up, it was already set up at a LFS, so it already had a few little scratches in the glass, but since then, I've added quite a few more. I have a mag float, and it has a habit of attracting pieces of sand or rock from my sand bed, and by the time I notice, I've already scratched it more. I was wondering how you clean your glass in order to avoid this. I know now that if I'm going to keep using the mag float, I can only go so low with it, not all the way to the sand bed like I'd like to. Do you guys actually use these or is there something else that you prefer?
