Transferring fish to main right after Cupramine treatment
I purchased a yellow tang and a flame angel about 5 weeks ago.
I placed them both in a 10 gallon quarantine tank and 2 weeks after I got them I noticed the tang had ich, so I decided to treat with Cupramine. Tomorrow will be the 21st day of treatment which means I can start removing the Cupramine, here's the question.
Can I do a 5 gallon water change tomorrow morning and then in the afternoon transfer the fish to the main tank after a short acclimation.
The salinity is exactly the same and i'll match the ph, mainly through acclimation, but if it's far off, I'll adjust the ph prior to transferring them.
I know the main concern is the fish will have copper on them, but would it affect my 90 gallon tank?
