Can Marine Ich stay alive on dry goods?

[George]

To be safe, let QT equipment dry for more than 24 hours before reuse them on anything else.
If you are paranoid, use bleach or any chlorine solution to clean equipment and let them dry (for bleach to evaporate rather than for marine ich to die).
If I were you, I would let the DT to go fallow for 12 weeks.
Good luck.
