The only reason that the tubing and NOT the reservoir is showing the greenish haze is because tubing is far more porous than the materials used to make your reservoir, or even your blocks/fittings, ergo the green colour that is probably coming from your radiator is, showing up in your tubing

What's making your water that green color, doesn't look like the tubing is causing it. Usually green water means that you're getting copper in your water so something is breaking down. I'd take apart you loop and and see what's causing it.
Some information on the 'Green Topic' that i had posted a few days ago in the OCN Cooling Club and pic Gallery:
EXCUSE THE OT
Secondly, as far as i was aware, certain coolants actually lower the loop temp and are also quite neutral in their Ph content-my advice to you would be to PM Mick on his thread (Mayhem's), im sure that he will offer you any suitable advice if he can-he's good that way.
The green corrosion is called patina, it is basically tarnish that occurs on the surface of copper/bronze and similar materials when the metal is exposed to various chemicals or acids and in turn oxidation takes place.
Have you had a look at the Ph of your loop (ideal Ph would be around 7 which is neutral), you can get Ph test strips very cheaply at any drugstore.
'Acid' (soft water) water being under Ph 7, and Alkaline water (hard water) being over Ph 7 (i remember this from my old days when i was an Aquarium enthsiast-now those were kick a** pumps
Anyway, here is a link to simplify what i have said: http://ga.water.usgs.gov/edu/ph.html
that may well be the cause of your 'Green' problem.
Hope it helps you solve your 'Green Problem' Edited by kkorky - 1/31/13 at 3:58am
