sorry if this is in the wrong place but i have been trying to find some answers to questions that i had, but have come up empty handed. any help would be awesome. First off here is what I am using: AquaXtreme 50Z-DC12 1/2" everything Swiftech MCRES-Micro Hi-Flo Reservoir Danger Den Maze4 Acetyl GPU Water Block Danger Den Maze4 A64 CPU Water Block BI Xtreme II Dual 120mm PC Radiator You may have seen my setup here: However there are a few things I am not sure about: When I filled my system, I followed all the guidelines and made sure I got all the bubbles out and everything, used distilled water, yadda, yadda, yadda. But there seems to be some sort of metallic flakes in the water when I first filled and started the pump. Is this normal? Should I bleed and flush to get out everything or has anyone seen this before and it’s been ok? Which leads me to my next problem, how do I bleed and flush a system without killing my pump? Any pointers here would be great! Also, does anyone recommend any additive to the water to make my system run better or help the pump and or retard corrosion? I don’t want any UV stuff or anything like that, but I would like to know if there is anything that would still keep the water clear, but help a bit. And I think that is it. I am leak testing now, but if I have to flush and bleed, I would like to know before I get all crazy! Thanks everyone!
