I just have a few questions. I noticed ich on my potters about 3 days ago and since then i have been treating his food with garlic. I was wondering how long i should be doing this for and when i should attempt other means of curing the ich? Im not sure what caused it, my water paramaters are all good. It could have possibley been from when i did the last water change. I may have added the new water too fast. The tank dropped like 3 degrees. That could have shocked him enough.
