I have a MCR-320 and 220 + a D-Tek Fuzion V1 (Both copper, so no problems with those), but I'm thinking about buying a Koolance res.? Will that give me a problem with corrosion?

I'm thinking about buying either the Koolance fluid or the Feser One (F1, both blue). Will that work okay? I have clear coils so I need some colour to get the piffy look over the WC-system.

Distilled water isn't easy to get your hands on here were I live.
