Identify Swiftech Mico Res stains

post #1 of 5
Thread Starter 
Take a look at the 2 pic below. Mysterious orange-brownish stains have been appearing on my Micro res about several months ago. I do not know when it first started as I have the res mostly wrapped up (to minimize heat loss as I am running a chilled loop). A few months ago I did an inspection and found some stains. Now, the stains become a little more.

Stain peculiarity:
a. appear only along joints (eg Arrow C) and not on a flat surface (eg on a vertical wall surface)
b. Arrow A shows that the stain is near the outside of a joint (not in direct contact with the coolant). So, the stain can ''seep through or penetrate into'' the joints to reach an outer location?
c. Arrow B shows that the stain is found at the top near the inlet screw hole. There is no coolant direct contact at that position as well.

I am speculating coolant 'vapour' react chemically with the glue of the joints. But this is something I have not heard of.
Any idea?

PS Coolant is a glycol based coolant, with anitcorrosion / antifungal additives.

First thing I have to say, Stop using dye.

Most likely reacting with the glue like you said.

Go grab a bottle of distilled water and a kill coil or some PT nuke. That is all you need.

Hope it is not evidence of corrosive deposition.

If so, how do those tiny tiny deposits get to the positions B and C?

I don't know but my MicroRes is cracking. I never got any of those weird deposits you have and my reservoir is 4 years old, looks like the only thing you do different than I do is use additives. I am always against additives because most pumps are made to pump water and not some chemical sludge solution. They also are difficult to clean and stain tubing so I don't use them.

I only use PT Nuke and distilled water, maybe I will incorporate killcoil into my MicroRes but that's about as far as I go with water cooling.
