I have been batteling fungus outbreaks for about a year in one tank. 2 nights ago i noticed some of my fish had a lil cloudy eyes so i shut the UV light off and took the carbon out. I added the reccomended dose of melafix and pimafix, now all the fish have extremly cloudy eyes and i don think they r goin to make it. any suggestions? i have been dealing with outbreak on and off for over a year.
