Observation period after copper treatment

[icliao]

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.

I recommend 2 weeks after treatment. But that is with the 100% guarantee that all ich including from gills have been killed/rid off. That recommendation is for somebody who knows what they're doing. Otherwise for new hobbyist 3 to 4 weeks after treatment is over.

So 4 weeks observation enough after the treatment?

 

[icliao]

I did treat the fish 30 days then move to a clean tank for observation

 

[Dr. Reef Verified Sponsor]

Yes 4 weeks is good enough.

 

[icliao]

Thanks. Good to hear since time running out

4 weeks should definitely put you in the clear.

I observe for 14 days post treatment also.

Thanks. I was considering black molly test in the observation tank. It is perhaps unnecessary.

I've been doing 14 days after cooper treatment with no traces of copper in the tank.
