What is the fastest and best no-scratch
way to clean green spot algae off an acrylic tank? I made the mistake of not doing a wipe-down on my acrylic tank for two weeks. Now, it's taking forever to scrub the green spot algae off using a soft washcloth!
Any better way that does not risk scratches? I read the "Member Submitted Article" regarding cleaning acrylic. I like the idea of using an an old credit card and I have a mag-float I us in another tank, but I'm seriously worried the mag-float will scratch the acrylic.
