Ah interesting, I did notice the glycol component in a lot of premixed solutions. Maybe I should just buy something designed for the purpose. I've been turned off reading all the horror stories of gunked up loops. Of course it's hard to know if those are cases of user error or a bad batch of solution.
I feel similarly.I'll just be using a kill coil. I know some don't recommend using it with Nickel, but that's mainly due to EK's massive fuck up about 10 years ago with their shitty plating. I ran it in my build back then (2011 or 2012 I think) for over a year and never noticed any issues. To be on the safe side, those solutions are nice though.
I'm planning to use DI water in my upcoming build. Just curious what the recommended biocide agents are?
Do I need to do any pre-flushing/cleaning of all the components?
