Tunze magnet cleaner

[Demonic]

I was just curious as how to tell which magnet I have. I just bought a package deal on a tank and it came with a Tunze Magnet cleaner. It is super, super strong and was wondering which model it was. How do I tell with the untrained eye?

The color of the felt is the main give away, green felt is 0220.53, blue is 0220.54, white is 0220.55 or 0220.56. To determine between 0220.55 and 0220.56, the 0220.56 will have an inside and outside half of equal weight. On 0220.55 one will weigh substantially less.

Thank you, I am thinking I have the 0220.55. Still not 100% sure though.
