Man, you are in a pickle. Forum members are going to want to know the following;
Basic water parameters, nitrate, phos, etc.
How much temperature swing does the tank have during the day?
How do you make your salt water?
These will help figure out a way to prevent further damage as these diseases are often brought on because of poor living conditions.
There are some "reef safe" meds you can try, need some members to chime in on this.
