I'm looking at setting up a single loop for my cpu. I've looked at quite a few documents and posts relating to coolant and additives. I'm looking at adding color to the loop but wasn't sure whether to use UV reactive fluid such as Feser, distilled water w/ dye, or distilled water w/ UV tubing. I've seen the bad and the good comments about each, so I'm still undecided which way to go. I've read UV reactive fluids and dyes may clog the system and UV tubing has a tendency to not glow. So, any suggestions will be helpful.
