I recently had an ich outbreak in my tank, so far the six line wrasse and one of the clowns look the most I impacted. The spots have come out most on my six line and starting on my tang. I’m planning on setting up a 20g and putting dividers in the tank. I would have to do an in tank cycle so can I use prime while medicating with copper at the same time? Or would I have to stick to constant water changes? 4 fish would be treated total, any help or advise is appreciated
