Mighty magnets are awesome. They have removable, replaceable pads unlike magfloats. Come in a variety of sizes and are acrylic safe. They also have acrylic scratch remover pads.

Ive tried almost everything and razor scraper seems to work best for me. Its worth spending extra money on a decent one that is comfortable to hold. That being said big mag floats and other brands are great and easy but can easily get sand or small gravel stuck in it and you dont notice till you go to clean and hear the scratch
