Inside of tubing gone white

So I've just restarted work on my WCing after a 5~ months due to getting put off that I had killed my MB/GPU/RAM (turns out I may have bent a few CPU pins) and have opened up the system to clear out water I may have left in there (only rads, res and one pump, no blocks and not connected in a loop). Got some out of the front rad (was water I had been using, deionised from supermarket + biocide) but noticed that the inside of my tubing was white.



Can't see anything like this on my UV green tubing that's been sitting on a bench since I disassembled the loop several months ago but I noticed a buildup of black stuff on the CPU block when I went to lap it to clear off the liquid metal (at least I remember seeing a darker area, didn't have much luck cleaning it with a toothbrush when I tried iirc)

Would this be just plasticising or could there be algae because I left the loop a lone for so long? Recommendation for replacing tubing or cleaning? I was going to run pure deionised water through rad/tubing for a bit then some more with biocide in it before I connect up the blocks but should I do more?

Tubing is so inexpensive I'd replace the tubing. What coolant were you using?

It sounds like plasticizing which is usually white, is there anything in any of the rads or other components when you flush them?

Using deionised water from carplan + pulse modding PHN bioclear, can't see anything in the water that I got out but I haven't fully flushed them yet.

Just replace the tube, darkened areas on Copper blocks is fairly normal. If you've toothbrushed it I would say that's sufficient to remove anything that would cause issue.

Alright thanks for the help, btw nothing came out after i had run a litre through the tubing and rad. So what's the current recommendation for 10/13 tubing? Ideally black but it's out of sight so colour doesn't matter, currently using XSPC for both 10/16 UV green and 10/13 black tubing iirc

EDIT:: 10/13 Was Alphacool tubing

EDIT:: Went and brought a retail box of Masterkleer 10-13mm UV Green, seemed like the cheapest good brand available.

That is plasticizer,unavoidable for regular tube users im afraid,change tube regularly and keep an eye on flow rates as the plasticizer can sludge the jet plates of CPU blocks.

The black on bare copper is copper oxide,its a good corrosion inhibitor,if you cant see it then leave it as it will protect the copper from corrosion.

primo advanced LRT is good stuff

the white is also normal from some biocides specially when a tad to much may of been used.
