If you want to use Feser fluids, just use it straight with no extra stuff. You cannot expect nothing to happen, that's just plain silly. I'm not really sure why everyone seems to be so surprised.
Then the solution is to flush the system and re apply the feser view with distilled without adding the Pt-Nuke?
