Official EK statement - Nickel Plating Issues

[zalbard]

Certain chemical additives based on pure silver and Copper Sulphate that were added to the loops all of these cases have made distilled water electrolytic and with its properties they caused corrosion of nickel plating.
...
EK recommends only coolants with anticorrosion additive, although our internal test systems of pure distilled water have been found without any problem in 2 months test period. EK Team would like to ask you to kindly spread this information as we would like our users to continue having excellent experiences with EK products.

Please make something clear, Eddy. Is "PrimoChill Liquid Utopia Protective Fluid" completely safe?

PrimoChill's latest water cooling fluid innovation Liquid Utopia, offers a full line of protection against algae and corrosion when added to new or existing cooling loops.

So it's supposed to protect blocks against both algae and corrosion.
Could be a good recommended additive. What do you think?
