Mystery build-up in res

post #1 of 7
Thread Starter 
This is a newly-build system and has been running for about three months. I was draining the loop in my rig this weekend and noticed some buildup in the resevoir. It looks like tiny bits of white particles floating around in there. Then I noticed that the res filter had this greenish buildup on it. I cleaned the filter but it's pretty obvious that I'm going to have to do some major cleanup soon. I'm trying to figure out what this is.

My setup:

Switftech rads
Switfech Apogee Drive II
Switfech Maelstrom 5 1/4" Dual Bay Reservoir
Primochill Advanced LRT tubing
EVGA GTX Titan Hydro Copper

I'm using distilled water with a Feser-based biocide mix. No silver kill coils in the mix.

Before I tear the whole system apart and start replacing stuff, I'm trying to figure out if this is a tubing leech issue or if I have an algae problem or perhaps something else. I'll see if I can take some pics later today, but for now the tubes look nice and clear. I'm wondering if I had some algae growing on the roof of the res and the turbulence from bleeding the system disturbed it.

Greenish stuff most likely is algae, but the white particles without a doubt are plasticizers leeched from the tubing.

A flush and cleaning is in order...you could have loads of it built up on the pins in the blocks.

I agree, but I'd like to figure out what it is before I do all of that. I don't want to reproduce the problem again in a few months. ie; do I need new tubing (I understand that the primochill advanced wasn't supposed to leech)? A new biocide? Different coolant? Hopefully some pics will help.

You flushed out your radiators well before using them , right? Radiator flux is usually green as well. The white stuff is possibly plasticizer or else that feser stuff is breaking down. You didn't add anything to your coolant except distilled water and you never rinsed anything with something besides distilled water (or heavily rinsed with distilled after using something else).

post some pics if you can.

Not a great shot, but it shows the scum on the top of the res.

I have two radiators. Unfortunately, I only flushed the second one that I added to the system. It's my first build and didn't think to rinse the original. When I did rinse, I used tap water and then distilled.

As a followup, I checked the tubing that I removed, cut it open and found no traces of anything...
