Hi everyone. I have been dealing with problems in my tank since I lost my cycle due to a power outage.I tried to keep ammonia and nitrites low for my fish, but still lost one after the process of cycling. The 55 gallon tank has been cycled again for nearly a month.Ammonia has been at 0 nitrites 0 and nitrates around 10 ppm. I bought a new fish that of course looked healthy...that now has a few white spots on its tail. I have never dealt with ich. I have of course read about it. What is the best ich medication? Is it difficult to get rid of? Thanks in advance for your help.
