Does UV Coolant/Dye Leave Stain/Residue/Gunk in Watercooling Loops?

I've been thinking about using Feser One Cooling Liquid or PrimoChill Non-Conductive Coolant for a while now. I haven't used watercooling before.

I've seen both sides of the story posted on XS.

1. I've used x brand coolant, and never have had an issue so far.
2. I've used x brand coolant, and it has stained, left residue and or gunk in my waterblocks/tubing/pump/radiator.

I've also seen a point being made that the cause of the staining, residue and gunk in loops is from the mixture of biocides, corrosion inhibitors and anti-freeze together and/or with UV coolants, in which certain chemical reactions occur.

From what I've been told by experienced watercooling guys, PT Nuke + distilled water is the best, and is probably what I will end up doing.

It seems you have already answered your own question?

But what I can tell you with 100% certainty, is that running only biocide and distilled will not leave any gunk. Use colored tubing if you want color/uv. I'm buying some of the blue feser next month instead of paying/adding fancy coolant.
