I have 2 150's with 1/2" acrylic and have been using an brush inside the tank but I can't stand doing that any more (too hard, uses muscles I must not use otherwise
and can't see what I am cleaning, no way another member of my family will help) so I want to get a magnet but I haven't liked the mag-float ones for smaller tanks.
Has anyone used an "Algae-Free", Mighty Magnet, or Magnavore one on acrylic and been happy with it?
Thanks in advance.
