Actually I been fighting the cotton mouth disease in my Regal Angelfish for about 3 weeks now but still shown no improvement...Another tread said that the API Melafix can cure I been using it about 40% of the treatment already but still no result and I hardworking change water to the top condition and checked the parameter everday. Any recommended to this disease ?

Cotton mouth is often fungal. I'd try Furan-2; its good for both fungus and bacterial infections. Mela-Fix is not a cure for anything, IMO. Nitrates at 80ppm aren't going to hurt fish; but not good for inverts. How big is the Regal? The QT? Did he arrive with the mouth problem? Any other symptoms?

yea the regal now is bout 5 inches in the shop it was great but inside my house the next day disease spotted.

Regals are one of the toughest fish in the hobby to acclimate, often refusing to eat. IMO & IME, the origin of the fish has a lot to do with it. Did you see the fish eat at the LFS? BTW, many Angel species are tough to acclimate as adults; probably because they've already established a diet that includes things that are hard for us to duplicate---especially sponge. I'd try one of the frozen angel foods that contain sponge----it might get him eating, doubtful if the cotton mouth has been treated and not eliminated. Sorry to say, doubtful even if it has. Have you treated this fish with anything else but the Mela-Fix yet?
