Tap water, distilled water, de-ionised water? Or are they each safe to use?
I have just taken delivery of a Zalman Reserator XT system
It comes with Zalman Anti-corrosion coolant (I guess their brand 'antifreeze') which needs diluting 4:1...
I thought that the best water to dilute it with would be distilled water. I went to our local store and bought some - I had asked for DISTILLED water...They gave me a 5 litre container & when I got home, it was de-ionised water. I have just returned from town searching for distilled water. No one stocks it, only de-ionised stuff. I tried pharmacies, car-parts dealers et al (I even tried to cadge a litre from the local hospital

)
As I am keen to get my water cooling system up & running, I am wondering if the de-ionised is in reality, OK to use?
Advice please
