This is what she told me. Best for Fish!
Increase temp slowly to 86-88F
Increase water changes and gravel vacs atleast 3 times a week. more if possible
Leave temp up for at least one week after last spot is seen
Slowly decrease temp to normal
You can add a little salt if you like. It can help avoid infection in the sites where the ich leaves the body of the fish. Plenty of clean water helps a avoid this also.
