Update decided to give the tetra parasite guard a try. Figured it could not hurt anymore than watching them die from being eaten by parasites. Lost another 2 of my biggest clowns so that pushed me try. Why is it the biggest ones go first? the microbe lift stuff did not seem to help at all, seemed to be more anchor worms on fish. Hope for better results with the parasite guard. A lot of people say dimilin and the parasite guard has the avctive ingredient diflubenzuron that's in dimilin.
