    Copper?

    Anybody have bad experience using copper? I bought some new fish and watched them in a new QT tank for a week. No signs of any illness at all, but I decided use copper for two weeks and added the recommended dose of cupramine for the first time today. Well, I just found a tang and a mandarin on the brink of death. I moved them into a fresh batch of water and put a bubbler in. I put some cuprasorb into the QT tank and did a partial water change. I know copper is a toxin, I know hypo is supposed to be safer, but after 8 weeks of hypo, I lost all of my fish when the power to the QT tank went out. I didn't want to wait another 8 weeks of hypo and have a PH issue and lose them. I don't want to add more copper and kill something when I'm trying to help it. Sometimes this ain't what it's cracked up to be!

    I never had luck with cupramine, I always ran paraguard. Try starting the copper at a lower dosage and slowly raise it up as the fish adjust

    No... The mucus layer that scale-less fish have and shed regularly helps prevent the parasite from burrowing in and what have you.

    I have had some issues with copper taking out fish, I've stopped using it completely. When I QT at home I don't treat, but if someone pops something, I then convert over into a hospital tank and treat accordingly. I thought the QT was a way to force hidden symptoms out, not preemptive treatment. Sometimes the treatment is as stressful as the disease. I also like a FW dip to determine if it's actually ich, velvet or another dinoflagellates.

    Copper?

    After talking with Brian at the meeting today, I am certain it was user error with the copper. I had used some Prime in the tank the day before I dosed copper. It paired with the cupramine to make it highly toxic. Well now I know.
    Don't look here for a comment.

    Here is the FAQ I found on seachem's website I was talking about Joe.
    " Q: I've been dosing with Cupramine™ and then I added Product X and everything died. What happened?

    A: If Product X is a reducing agent such as ParaGuard™ (or other aldehyde based medications), or if you overdose with a dechlorinator, such as Prime® then the Cu+2 will be reduced to Cu+. Cu+ is 10 times more toxic than Cu+2."

    Here is the link to the page too. http://www.seachem.com/support/FAQs/Cupramine.html
