I recently went through a bad Ich outbreak when I moved from a 380 gallon tank to a 600 gallon tank, the outbreak was so bad that the fish were completely encrusted with white spots and hardly able to see and after two days of running a UV sterilizer things look way better and the fish are eating and swimming around. I would definately recommend a UV sterilizer and a good skimmer for large tanks.
