To prevent corrosion in watercooled systems one should add something like Redline's Water Wetter which also increases the waters cooling abilities. This is especially important in systems where you have different metals in your cooling system. Like a copper block, aluminium reservoir and brass fittings.

The reason electrolysis happens is because the bindings of oxides are stronger with certain metals (alu) and weaker with others (copper).

It occured to me that earthing the components of the cooling system to a common ground could prevent electrolysis from happening. Is this a correct assumption?

Or would it just make it easier for the electrolysis to happen as the electrons can now more easily travel through the common ground?

Any chemists around that could clarify this?
