Recommendations for yellow tang

[tjmarty]

I have a Yellow tang that i bought three weeks ago he has been in the QT since and doing well untill today. He has red bloches on him witch appear to be a bacterial infection.
Does any one have any recommendations for treatment or medication would be best to treat him with .

I had the same issue in the past and it didn't need to be treated with medication. Simply do 20% water change and the red blotches goes away in about a week.
I think this is a water quality issue
