here is how i see it.
you put them in the
QT at first sign of problem (good call)
after this you continue to monitor, and at no point have you seen any sign of any pest.
since its been over a week with nothing, i "personally" would think its ok, and the
bleaching was likely stress related or something else. although if you want to be safe you could do a
FW dip first, or just leave it in there longer
