I'm usually extremely cautious with cleaning my glass, but lately I've been noticing more, and more scratches appearing out of no where. Check the glass scrubber, it's clean, no debris in it, no sand. So I can only assume sand is getting in it at some point and falling out. I use a magic eraser once a week at water changes to do a full scrub. I tried cutting a magic eraser and placing it on the glass cleaner. That didn't last long, it would either fall apart or the magnets wouldn't hold. The 265 is scratch less and I'd like to keep it that way when I switch over so what are your tricks or tips
