Confirmed: Feser 1 Blue Premix + GTZ = do NOT want

So if you use Primochill LRT tubing and Distilled, you add nothing else? I saw that earlier in the thread, but just confirming. Would you not add silver either? What about something like Water WetteR? Just plain distilled and nothing else?

Also, what's the maintenance like on going Primochill LRT + Distilled? Replace/clean every year? Every 6 months?

You have to add a biocide like PTNuke UNLESS you like green stuff turning your loop into it's breeding ground OR if you're going for an earthy look with your build...
