Nate, alternatively if what you say is true (I doubt it) then removing all of your acros and dipping like crazy will not even work. If the worms can live without food for as long as a year then it is impossible to conclusively prove that any tank is AEFW free, even the ones whose owners removed all the acros and either dipped them in Levamisole or threw them out. That means no one can claim that they are FW free and no one should trade.
