How to quarantine snails and clean up crew

[DenverSaltyFarm]

Im getting ready to do a tank restart due to all the pests my tank as acquired. lesson learned dips dont always work. fish and corals will quarantine in their own tanks before adding back to the tank and was wondering the process for snails?
I got a few pests from snail shells in the past and the only thing i can think of is doing a fresh water dip then hold them in a holding tank for 30 days to see if anything grows on them?

I think the general idea to prevent them carrying over fish disease at least is 76 day’s with zero exposure to fish or any contamination also including arosol transmission
