Update: After running the rig for the past week or so I've noticed the tubing starting to get cloudy (again). I took it all down (again) as a part of the final completion which will hopefully be tonight, and sure enough it looked like plasticizer build up, mirroring that of the pictures found in
this thread on OCN. I'm a little sad because I read a lot of that thread and it sounded like silver was causing the buildup, so I was careful not to put silver in the loop and only PrimoChill products. Well, it didn't matter and I got some buildup anyway. Here are some pics.
Tubing out of the system, as you can see the section where water was running is much cloudier than the section where the tubing was attached:
A look down the tube, you can see the stuff:
Cleaning em out:
I found that wadding up a paper towel then pushing it through with a long rod I found cleaned the stuff right off. I did a couple runs in each tube to be sure.
Now the tubes look brand new again, but of course they'll probably cloud up again in another week. Hopefully I got a majority of the stuff out, and it won't be too serious (don't want to break the loop down again unless I upgrade something).
That's it for now, I have stuff to do from 7-10 EST tonight but I should be able to get it done after that (depending on how late I stay up). If not tonight then tomorrow for sure.
