I just got through with a round of ich that killed my Blue Tang. Some treatments I used didn't help till I used Quick Cure. In the process, I lost my snails, but not my seastar;-) It's been 3 days since my last application and I've already done a 50% water change. How long should I wait before I can add another fish? Also, should I try to get another Blue Tang? They say that Blue Tangs tend to get ich alot and I'm hesitant to get another one. They are so pretty though and my youngest daughter really wants me to try again. One thing I've learned is to keep my temp at 83 degrees. The higher temps seem to keep the ich at bay. I think that might have been my other problem as to why I couldn't get rid of the ich quickly enough.
