I have an orange shoulder tang that was in cupramine at/over therapeutic levels starting on June 9. He was in this QT tank until June 18. On June 18, I moved him into a brand new, clean QT tank with water already at 2.5ppm using copper power. Today is July 10. So my question is, has the full 30 days in copper treatment been achieved even though I moved him from tank 1 (using cupramine at therapeutic levels) into tank 2 (using water with copper power already at 2.5ppm)? 9 days in cupramine at 0.5mg/L & 21 days in copper power at 2.5ppm. I don’t want to risk bringing any parasites or disease into my main display tank. What do you guys think? Thanks in advance.
