To avoid corrosion in the loop?
Copper, brass, and nickel are neutral to each other and so will not corrode. My house plumbing is copper, 45 y/o house, and no copper rust in my water.
There is nothing in your loop that will corrode in your lifetime if you keep only the 3 metals listed above.
If you feel your red water is warding off corrosion, and if that helps you sleep at night, so be it.
But pure water is the best thermal conductor, add anything to it, and you lessen it's thermal properties.

The advantage is corrosion inhibition. It's also relatively inexpensive and readily available.
RoboTech (Lee Garbutt) discusses some of the benefits in this article. It's an old article, though, so I am wondering what advances may have developed since then.

I also want to hear what specific coolant-tubing combinations tend to have fewer incompatibility issues.

Someone may have a great experience with a particular coolant, but if I am using a different kind of tubing, my experience could turn out to be much more problem-filled.

What about the titanium?

What about it? Do you have, or plan to have titanium in your loop?

Because yeah, titaninium mixed with copper, brass, or nickel could be a problem, absolutely.

As I wrote on page one :

Unless you start mixing metals in your loop, which will corrode, you dont need antifreeze.

Yes, as I said in post #8, my loop will contain titanium, so I presumably need an anticorrosive, which antifreeze provides.

Sorry, I missed that.
And yeah, the titanium will be acting as a cathode, and the copper as an anode. So you will get galvanic corrosion if not protected. And if you run a chiller, you will of course need antifreeze of some sort.

This is the water cooling forum, not the phase change forum, so I assumed you were WCing your machine. My bad! doh.gif

I had two silver coils running in my loop and had what looked like pond scum (white, fiber-y stuff, I'm assuming it was algae) forming in the loop, I'll never use just silver coils and distilled water. I buy premix solutions now, or make my own with alkylene glycol/'ethylene glycol and distilled water, about 25/75 mixture. you won't see any galvanic corrosion with that combination, and it should keep all of the bugs from growing

Well main reason really is that you get cheap color that doesn't fade with coolant unlike the premixed coolants and color additives do, and it should keep the bacteria away a LOT better than just plain water.

Otherwise stick with distilled water and kill coils. They work the best. Also, you don't mix coolants. Bad juju happens when you do that because you can get chemical reactions within your loops.

When I asked what proportions, I meant what ratio of anticoolant to water. I wasn't asking about mixing different coolants.

The guy that I know who has used it for a long while says he does 30% Coolant but I did 10% myself as I want minimal reduction in thermal conduidivity.
