Old Watercooling Rig having interesting issues.

Hey guys,

I'll get straight to point, I haven't payed much attention to my water cooled rig for a while now (1.5yrs +), I've been busy with a lot of things and it was always just working fine (I ran benchmarks every now and then to check all is OK and just peeked inside to see everything was fine). Today I did another check and saw that one of my of GPU water blocks had a load of crap in it, I have no idea where this has come from (usually whatever dirt Ive seen and cleaned in past has never been like this black smog) - so that's the main problem.

I'm going to be a bit cheeky and say that rather than a fix (the obv one being take apart my whole rig and clean everything), I'm wondering whether its OK to leave it as it is for now and then clean it later when I have time? Like I said earlier my benchmarks are all OK and the cards (R9290xes) run at reasonable temperatures when stressed.

Here are some images of the problem on imgur: http://imgur.com/a/Quji9

A side problem is that my water level on my reservoir always loses a very very small amount water every few months - I've already been on forums about this problem and the conclusion is that this problem is due to small failures in connections/micro leaks in components leading to some water probably escaping very slowly and evaporating away. Since trying to find the source of the failure is practically impossibly without replacing everything one by one which is too expensive/time wasting (yes, I've rebuilt the RIG a couple of times making sure everything is tight). The only negative being losing a little amount of water which is harmless as it evaporates off quickly (due the heated/high airflow conditions), I just refill a few ml of water every few months.

I hope you guys can either convince me my judgements are wrong/too risky, or tell me you think my suggestions are OK?
 
Solution
All that is normal since your not doing the required cleaning for a water system.
Draining and flushing the system.
Adding some more liquid from time to time is also normal.
