How long do I have to observe the. New fish after treated them with CP or copper and Prazipro. Is 30 days enough or do I have to go 6-8 weeks to be absolutely sure? I am asking this becasue I am going on vacation and only have 4 weeks to observe the fish after treatment.
 
Thank you for the reply. Was thinking about throw in black molly test in the observation tank. Perhaps it is completely unnecessary.
