Zerex - Good Or Bad???

[liquidfluidity]

I'm finally getting ready to fill my system and decided to check and see what % of mixes people are using. When I started reading threads , I found a few that relayed that there was a cloudy problem that happens with Zerex. Is this true and should I use something else? I have the Zerex and some regular old Prestone antifreeze. I want this to be a somewhat maintenance free set-up so I want something to last as long as possible without having to change the wtaer out - ever(LOL!. I would like to use what I have but which is going to work the best. My loop has no aluminum and contains only copper and plated brass and Delrin.
Any suggestions or experiences would be extremely helpful in assisting me in this decision.

Fill it with 100% distilled water and forgetabout it.

Did a bunch of research and found that a small % of people actually had the clouding issue. It seems to be an "odd Phenomena" with no known real answers. I'm wondering if it's from using tap water(minerals and such precipitating out) or using cheap tubing. I used Tygon and distilled with a 5% mix of Zerex(as directed By Danger Den). Guess we'll see what happens. Worst case - I clean and rinse the system and start over
