I been battling ich like crazy for the past week or so, now after LOTS of water changes with RO water and high grade salt AND after Ive run a ridiculously oversized skimmer on my tank for 3 days things are getting worse. I know this cloudy eye thing has gotta be bacterial but how can I treat this? Ive been reading that cloudy eye is most likely caused by poor water quality but how can that be!! Is it contagious? I bought a 240 gallon setup from someone and took his maroon clown. I didnt get a very close look at the fish cuz I was so busy breaking down the tank. After a few days in my tank I noticed the cloudy eyes. Now 4 out of the 5 fish I have left have it. Are they history? Any chance they can fight this off iff conditions and nutrition remain ideal? If I do have to treat this, will I have to set up a hospital tank and treat with anti bacterial?
