Look Buddy add salt, i've been keeping discus for a while now and if things get really bad a do a salt dip until he starts rolling then put him back in the tank. ADD THE SALT! trust me if anything it will save you much heartache to come. it seems weird at first i know but it does do a lot. its kinda like if you get a cut or something and you soak it in epsom salts. same thing except for fish
