Best liquids for a closed loop?

[JoeUser]

Going to be putting my new loop together next week. Thing is that it's going in a SilverStone SG08 ITX case. Tight space.

So I'm making it a closed loop and am interested in what I need to add or not add to my water to make it last and stay clean. I want like LONG lasting...months!

For right now I've order some Tygon tubing and a anti-bacterial silver coil to put in the tubing. I will be using pure distilled water.

Any advice is appreciated!!!

I've never had any problems with Koolance coolant - and they even have a low conductivity coolant available should you want it (though it is less efficient at carrying heat)

Phobya ZuperZero Coolant. Best I've ever used. I've used clear tygon tubing and after a few months, the tubes would turn murky with distilled water and a silver coil. With this liquid it stayed nice and clear and has lasted me for about a year now.

Distilled water with a killcoil or pt nuke.

Back when aluminum radiators were common you needed to use a mix (or just add antifreeze) to prevent galvanic corrosion. Silver can also cause corrosion (particularly to nickle coatings). I'm not a fan of the silver killcoils, the one system I tried it in went murky.

I've been using CuSO4 (blue PT Nuke) and plain distilled water without issues for years.

Distilled and biocode of your choice.

I use a kill coil and ptnuke.

I have always added a little antifreeze to be safe and even though I skipped having a reservoir altogether. Guess I just worried the barbs on the blocks would corrode over time.
