Flatworm problem

[cgh38]

Can anyone get rid of the red flatworms for ever? everytime I seem to get rid of them about a month later they comeback and I did dosed Flatworm Exit a week later everytime just in case some new ones hatched, how do you guys get rid of them? and also anyone know what happened to the Salifert Forum?
Thanks in advance.
