Does anyone know of anything that would be sticking to the inside of my tubes in a thin greenish layer? (Please don't tell me it's algae...) The stuff flakes off cleanly when I squeeze or otherwise deform the tubing it's stuck to. The tubes, once the stuff is flaked off, look brand new.
Here are two JPEGs to show you what I mean a little better:

Two possible problems with my loop that I've known about for a while:
1. I'm not certain if my loop is 100% air tight at the cap on the t-line (or the bubbles could be due to the following number 2)
2. The radiator traps air and sometimes circulates it around to the rest of my loop.
I think a lack of air tightness might cause things to grow in there, but I don't think random (sealed in) air bubbles would. In fact, I'm not even sure that the stuff in there is some kind of living organism. It shouldn't be any kind of mineral deposit because I used distilled water and glycol-based automotive antifreeze only (about a 60/40 mix of each, respectively). I specifically used a butt load of the anti-freeze to keep living organisms from appearing...
Regardless of what the stuff on my tubing is, I think I'm going to have to give my rig another full tear down and refit at Christmas. Water blocks are fairly easy to clean out, but the rad and tubing are more difficult.
Is there anything I can do to get rid of this stuff and/or make sure it never appears again?
Thanks for your thoughts, XS community...
