I have used it as prevention, I have used it as I see first breakouts, I use it when adding new fish, I use it on every water change and its been a good, dependable source to keep fish healthy. When fish are heavily infected with the disease this has not worked out for me, I only used as a preventative measure. If 7 days did not solve the issue take other recommended measures. Overdosing can stress the fish, use proper recommended dosage, if uncertain stick to a low dosage. Always read instructions properly Melafix and Pimafix have different dosage requirements. Its been faithful to me I would not hesitate to recommend to anyone if dosage is properly conducted.
