Aquarium Advice Addict
I think fishyfanatic already covered that. Maybe I am taking this wrong but when you wrote very very newbie question you came off as being rather rude. Personally not knowing what acrylic is would be more of a very very newbie question than the mag float IMO.very very newbie question. its a magnet, one half goes on the inside of the tank and the other goes out the out and you move it around the tank to get algae off. =)
