Dtek's "Supercool" water additive question

For those of you who have used it, does it change the color of the water? Does it smell? Does it prevent corrosion?

I've used a couple bottles before. The water color changes to a very slight light yellowish green. The smell isn't really noticeable unless you're takin a direct wiff from the bottle. I haven't tried Water Wetter yet, so I can't compare the smell, since I hear that stuff adds a foul stench. It's suppose to prevent corrosion, although I didn't use t for that long of a period. Temps were decent enough

You didn't happen to use any UV dye w/ it, did you?
