I think that is about old my tubing is. Honestly I have noticed this before on a different CPU block prior but just assumed it was normal oxidation because it came clean.

Everybody should stop using kills coils and use a fluid with biocide and corrorion inhibitor included. Something like Mayhems Biocide+ mixed with Inhibitor+ is perfect.

I wish we could go back & clean up all the bad info in these easy to find first time watercooler guides that're a decade old at this point.
time to shill for mayhems.
no silver, just biocide+and inhibitor+ and you'll have the cleanest system you've ever experienced.
I haven't heard about this one yet. Anyone have some articles/studies about this?
My understanding is that silver is inert and is used as anti microbial. I have always been wary solutions that claim to solve all. I'll be the first to admit that I'm no chemist so I completely acknowledge that there is way more science than black magic. KISS has been my method of choice which is why I've been using silver and DI water with only copper in my loops.

I have had this happen to a different CPU block before and it was the same black layer. It did clean up from the other block so I wasn't too concerned this time. I've just used a bit of vinegar and a tooth brush to clean it.
If the layer of oxidation is normal and is only a cosmetic issue then I won't sweat the problem.
Here is a picture of the GPU block that was in the same loop. It's been in use for 4-5 years with the same tubing, Silver and DI water(not the same water) without ever being cleaned. I would just attribute different rates of corrosion to due to different grades of copper used in the block.
