Ok, thanks for your reply Thequn. I'm on the fence whether to use a colored fluid or just plain distilled water. I might go with colored tubing and a colored reservoir tube. I don't have everything for my new build yet so I'm still looking around at different setups.
i use a 10-20% solution of coolant mix in every build, I tend not to fallow the rules. lol i also add dyes' but i cant see my tubing its all insulated now, because i am cooling it with ice and my reservoir is 5 gallons of water at around 1-5*c
Geez 5 Gallons?! How in the heck do you manage something like this? That's insane! lol I'd like to figure out how to put ice around an internal reservoir. I suppose I could mod a 5 gallon bucket and use it as a external reservoir. Do you freeze cubes of distilled water or is that where the 10-20% solution come in?
