Filled the system yesterday afternoon, not even 24 hours ago. Coolant is a mix of steam-distilled water and Zerex racing coolant. Not sure what the ratio is, but between two systems I've used about 2-2.5 litres of water and about 11 oz of zerex. Water is a nice(gag) pink color. According to cooltechnica, 11oz of zerex is enough to treat over 6 litres of water, so I should have plenty...

In the T-line at the top of the system, there are two little clouds, look just like the sort of stuff you get if you leave juice too long.

There was a small amount of brownish scum on the inside of the tubing used for the t-line; i ran out of new clearflex and had to use some I'd been using for testing. I scrubbed it off as well as i could reach with a pen, and couldn't see any more when I put it in the system. Neither ammonia or CLR seemed to have any affect on it.

How is this happening?? The system is 25 ft away from the only window in the room, and never receives direct sunlight, while indirect is pretty limited, as the window hardly gets any sun itself. I was under the impression that zerex was nasty enough to prevent things from growing like this, seems I was wrong...

What should I do about it? Drain the T-line to get the lumps out is obvious, but do I need to drain the whole system? Hope not, I've got no more zerex and I have to order it online... Can I add something to the system to prevent this from happening again?
