I've having a hard time battling velvet in my QT tank. I've been using copper power at 2.0ppm (measured with Hanna checker) which I believe should be enough to kill free swimmers. I remember copper power is therapeutic at 1.5ppm, which is the level I dropped my healthy yellow tang in at. Took about a day to raise it to 2.0ppm, but my new yellow tang somehow has contracted velvet from hippo tang, which was already battling it in the tank. I only combined them because I thought the copper would insulate the yellow from being infected by the hippo, but was that a rookie mistake? Is there anyway velvet can survive 2.0ppm copper?
For what it's worth, I have a fairy wrasse in the same tank, and I'm hesitant to go above 2.0ppm. He and the helfrichi firefish are totally fine. Does it make sense to move these two to a separate tank at 2.0ppm copper power? Then for the hippo and yellow tang, I would just do a FW dip, ruby reef rally bath, move back into QT tank, and raise copper to 2.5ppm over 1-2 days?
Thanks!
