How do you treat eye fungus?

If it is a true fungus, Quick Cure should have worked. Does the eye have fuzzy tufts similar to mold, or is it just cloudy? Cloudy eye is almost always a bacterial infection, so I'd recommend something like Maracyn 2, Furan 2, Maracyn TC, Maracyn Plus, Trisulfa, Triple Sulfa, or any medications with one or more of these active ingredients: minocycline, nitrofurazone, tetracycline, or acriflavine. Melafix is not a medication and still hasn't been proven to have any antiseptic properties, especially underwater, making it entirely ineffective against internal infections.
