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

[iddqd]

why not do distilled + a bit of propylene glycol? I have unlike metals in my loop... so without a softener, galvanic corrosion would eat through my rad, in due time.

E: actually, whatever because that's what i've been doing for years and never had problems. *shrug*

E2: it's cheap too, you can just buy the green antifreeze. that's what it basically is.
