Water cooling coolant and additives

^Yes, this is the best route. Even additives don't glow as well as you might think. They ultimately do NOT cool better than plain distilled and like you mentioned, many can break down and clog your blocks. If anything, dyes are usually safer than coolants, but I don't know of many that actually glow very well.

You could always go the old-school route and soak a bunch of yellow highlighter innards in some distilled for a few days, and then use that water in clear tubing under a black light.

We used to do this with liquor bottles in college when they were empty...and the put them on shelves in front of black lights and then continue emptying more liquor bottles...

I'm looking at either a yellow or blue colored loop. If I were to go with UV tubing, what would be the best method of gaining a colored tint to the water in the reservoir? LED?

Both yellow and blue UV reactive.

Yes, an LED would give a nice glow to your reservoir.

^^ What they said.

Distilled water, kill coil, UV tubing and LED for the res. Nothing is worse than ruining hundreds or thousands of dollars worth of electronics and because you thought that coloured fluid would look cool.

I actually did the pricing using the UV tubing and coil but with all the posts and reviews contradicting one another, I figured it's best to ask before wasting time and money.

Also, I wouldn't need to add anything other than the killcoil to the distilled water? No corrosion blocker?

No corrosion as long as you keep aluminium out of the loop.
