Best UV reactive dye ???

post #1 of 4
Thread Starter 
I did a search beforehand to see if somebody else has already asked this question, but didn't get any posts from the search ... so here goes.

I'm looking for a good UV reactive dye additive that i can add to my deionized/de-mineralized water. I've already got a great industrial biocide that will handle the sludge ... now I'd like to add in some color for the purpose of being able to catch those elusive leaks before they become a problem.

I'm wanting to go with two separate colors since I will have two separate loops. Red and blue are my first choices for these.

Does anyone know if "Liquid F/Xâ„¢ UV water dye" is a good brand ?

Pentosin G11 (Blue) and G12 (Red) are pretty nice UV reactive additives.

Check it out:

Pentosin G12 Coolant Additive ("Red" - UV Reactive) - 2oz.

NEvolution - I'd looked at those, but the pink rather than red was a let down for me. I really need something more akin to a deep fire red.

All I really need is something that is UV reactive ... it doesn't need to have any inhibitors or such in it since I already have the industrial strength stuff here at home.

Hey Joe...I used to use "Tracer-Line" UV dye you can get it at Auto stores they use it for rad and block leak testing...I don't know if it comes in any color other then blue thats what I always look for...Here is a pic of it in my old res it lights up pretty good...
