best performance for WC coolant

[nitromullet]

no it looks like its oxidation related, but i haven't found a conclusion to it. copper and brass and silver do not react with distilled water. you will have even more problems using PTnuke or hydrx or any other mixture of any liquid other than only distilled water in your loop.

Thanks for the clarification.

Since you are using the kill coil, I assumed you didn't have a problem with algae. As I understand it, there are two primary problems: algae and/or oxidation. Hence, I asked you if you had an oxidation issue. Apparently, you do.

The solution to the oxidation problem is to add some coolant, like Pentosin or HydrX.

Of course, the side effects of this is reduced performance and the possibility of residue build up in your loop. Perhaps the unwanted side effects can be mitigated by using a lower ratio of coolant to distilled. I dunno.

unless someone comes over here and does some chemical tests to tell me that was a result of oxidation, there's no real answer. Unless you know something i do?

I had no algae in my loop whatsoever. the water and tubes and reservoir were crystal clear.

I was just working on the assumption it was oxidation because that's what you said it was.

I don't doubt you don't have algae though. You are using a biocide, so that makes sense. You could have oxidation though because you are not using anything to prevent that. I get that copper, silver, and nickel are not supposed to react with each other, perhaps something else is causing the reaction? Or perhaps it's not oxidation at all... Maybe it's something else.

Really, what we're talking about is sort of key to what I want to know. Conventional wisdom and the experiences of many indicate that in an all Cu loop, distilled + biocide is all you need. However, your case seems to defy that notion... So, I'm curious as to what might be causing the issue and the solution.

Laboratory grade distilled / deionized water is mildly corrosive and slightly acidic. Pure deionized water is considered the universal solvent and can be very aggressive on most materials. Silver is much more noble than copper. If this type of water is used without an inhibitor, it could start a galvanic reaction where the copper is reduced upon the silver. (basically the same as aluminum reacts towards copper) Once the reaction is started it will only get worse.

You should only use regular non-deionized distilled water if you don't use an inhibitor. If you do use an inhibitor, deionized water is actually better, especially with high energy electronics like sharks with freaking laser beams.

I've used distilled water + Dtek coolant and that hardened the tubes and clouded them up. I've used Primochill PC Ice for a while now and it doesn't harden the tubes or leave any film and it SAYS it doesn't contain harmful chemicals like ethylene glycol, etc. No algae or corrosion either.

I'm not sure why I didn't ask you this earlier, but how did you clean the stuff off of your blocks? Does this require disassembling the block and scrubbing it, or do you just flush the system a few times?

oxidation usually occurs outside the wetted parts.

The wetted parts should not oxidize.

what is the best brand for water cooler coolant?

An absence of coolant.

Distilled water is best.

In my loop, I have a copper block, DD Fatboy 1/2 ID barbs, with distilled water and it's still clear.
