Honestly the layer of oxidation will have a negligible effect on performance while the same cannot be said about some inhibitors so just run with it.
The people who panic over this sort of thing would drop dead if I showed the inside of my old d-tek fuzion gpu. That thing is almost vanta black inside after being in use for 10+ years and its never seen a kill coil.
There is nothing to clean up. They do their job simply and well.
Cool. That's what my limited research was yielding as well. Since there are no chunks and its all superficial surface corrosion I'm not going to worry about. I used to fold on my GPU as well. It went for about 2 years straight so the "extreme" oxidation from extra heat and 3 years of neglect would make sense.

also, if i remember correctly. They can help accelerate your water's ph, specially when using nickel... It's been a few years, I'll see if I can find the data.
They're worse than worthless, as by doing nothing (at best) they're destructive.
I personally have never had a bio-mess, though I have never tried using anything other than silver and DI H2O. I have had bits of detritus and lint from poor loop cleaning/flushing and some surface oxidation apparently. Also couldn't say I ever tested the pH levels.
I have avoided nickle plated blocks because of the nasty flaking issues a few years back. I saw zero need to add extra bling and risk to my loops since I'm water cool for the performance/reduced fan noise.
If you find any of that data that would be awesome to share.

Glad to see there are others that have the same experience with raw copper as I do. I hadn't noticed any appreciable change in the performance of the loop though I never kept records of what it was like new so I can't say if i had or not.
Given the general consensus is that it's likely not the Norprene but rather the use of silver vs regular oxidation I will make a note in the original post.
