3 weeks ago I changed filters from an Eclipse 3 to a Millenium because I was not satisfied with the results. My tank had already cycled when I changed it. A week after I changed filters my ammonium spiked and my tank started to cycle again the problem is it was stocked so I had to treat the spikes. Some of my fish are looking sickly, but my water quality is back near perfect. Allmost zero ammonia and nitrites. Do you think my fish will start to get better when the water quality goes back up? Any help would be great thanks.
