Credit card/razor/mag float. If you have an acrylic tank don't use a razor because it can scratch the crap out of it if not done correctly. I used a credit card for rounded corners. Hope this helps
Cheers

Yeah mag floats work - however be careful. I've heard about some of them scratching acrylic. Somewhere there are "mods" for them to fix this.

They make acrylic safe magfloats, there blue.

Or I use a scraper like the kent one, reminds me of my car scraper. Works great!!
