Does Kanaplex need to be removed or does it go away on its own like metroplex and prazi?

From the SeaChem website:

After Treating​

When the treatment period is over, KanaPlex™ can easily be removed using activated filter carbon like MatrixCarbon™. It does not linger in the substrate or filter media of the tank.
So, I would remove.
