Yes the medium and small floats.. But not the max.
@cody.. I use it in my 3/8" amd while yes, it is strong, it's not overly difficult to glide around. Now that being said.. I have been careful to not let the mags seperate and then 'slap' back together. In other words, I hold the mag in position inside the tank glass and carefully let it attract the outer portion.. Although it has gotten away from me a few times and I have had it snap back without damage. But who wants to risk it really?
