So I've been treating a sixline wrasse in my quarantine tank with hyposalinity--but haven't been faithful enough to keep the salinity low enough. The ich had disappeared (or so I thought), but it was probably just in the dormant stage (don't know if dormant is right word, but I don't have time for formalities). Today I noticed that the little white scars are more present than ever before. I've been looking around on WWM for the best method to treat ich, if there is such a thing. That site is full of good info, but requires so much thorough reading. I don't have time to sift through all of the bs-I fear time is my fish's enemy now. What is the best and most effective way to treat for ich? I'm considering treating with copper--unless someone else has a better idea.
