Best biocide?

[EmoChipmonk]

So I was looking at getting the items for my coolest and all pt nuke is sold out like every where. What other biocide is really good. Or worst case is the least problematic concentrate solution.

Silver is a natural biocide if worse comes to worse.

I generally use EK Cryofuel premix if I can find it but any other additive might work just as well if used with distilled water. You can also use coolant antifreeze like a G12+ or G13 or in general the orange stuff. However you need to lower the ratio if you want to use it in your pc. I've refilled AIOs with a 10 percent mix of antifreeze and distilled water. Also make sure the flow rate is sufficiently high. Higher pressure makes it harder for algae to form colonies. Make sure to flush the system every 6 months though, 12 if you are lazy.

Been using dazmode protector for several years now without a water change and the liquid is still free from growth. It's mostly ethylene glycol with some corrosion inhibitors.
