Hi,
One of my goldfish is having cloudy face and eyes. I've checked the water paremeters: Ammonia = 0, Nitrite = 0, Nitrate = 0 using the API master Test Kit. The cloudy stuff comes off after a few hours when I applied salt into the tank but it keeps on coming back. I'm not sure what is the issue or how to treat this. Is this ICK or something else.
