Hey all! I put together a custom (well, from a kit) loop for my i7-3930k a couple week ago. I've noticed over the past few days that the tubing and/or water have a decidedly yellow-brown tint to them. Now, when I was putting things together, I noticed that the tubing was slightly yellowish, and I saw reviews to that effect, but things seem more colored than before. When I assembled the loop I put a few (four or five) drops of Dead Water into the reservoir with the deionized water--I assume that should have been enough to kill all life forms? Is it possible that my loop is brownish because there are things growing in it? If so, what would I need to do? Would more dead water be sufficient, or would I need to drain it, clean out everything, and then re-assemble it?
