Biowheel With Magnum 350

[DirtyHarry]

I heard biowheels can be used with a Magnum 350 filter? Which biowheel would work best and how would it connect with the Magnum?

The bio wheel comes with the 350 pro, I'm not sure if it's available as a seperate item; http/www.marineland.com/products/consumer/con_magnum.asp
