yep, only way to be safe, quarantine for 4 weeks to make sure you don't bring ich or worse, marine velvet! It can take as long as 4 weeks before marine velvet develop enough to kill all your fish and 2 weeks would not be enough as the parasite could be on a fish but in small quantity and the life cycle of ich or marine velvet is around 4 weeks.
I beleive that you probably introduced some disease, either internal parasites or bacterial, with the new addition of fish, so you should leave your tank empty of fish for 8 weeks now to make sure what ever is in the tank will die off without a host.
