Ionized water is corrosive to metals, as it contains sodium or chlorine ions that create an electrolytic solution which aids in the transfer of ions between the differing nobility of metals. The liquid-cooled systems I worked with in high power electrical controllers had to have de-ionized water for coolant.

We had one customer recharge the coolant of a 4kV, 6000HP VFD using a water hose and regular chlorinated drinking water. It took about a month for it to 'rust' out inside and corrode a hole in the water jacket that sprayed the VFD with this water. Ka-Boom! That made the 10MVA feeder transformer jump off the ground, breaking its pad mounts.

Someone on another forum suggested placing a few old real silver coins with high true silver content in the reservoir. It is the only suggestion I can remember that didn't have negative comments. I haven't tried it because I am not familiar with the internals of the chiller's reservoir and I want to make sure I wouldn't put it in a position that would restrict the pump intake.

I mentioned the silver coins in your tank a few months ago, Please google silver water and watch a few clips.

From what I can determine from my current research, the power level and more important, the wavelength of these aquarium UV sanitizing lamps are of insufficient power and incorrect frequency to generate ionized water. That's encouraging for this project. The lamp arrived yesterday, much larger than I expected, a bit shorter than one meter long, with inlet/outlet ports larger than my tubing. All that means is a pair of tubing couplers to adapt to the smaller stuff.
